Executive Summary

Quantum computing is widely viewed as a revolutionary technology for pharmaceutical research and development. IBM – one of the pioneers in commercial quantum computing – has aggressively positioned its IBM Quantum platform to address key challenges in drug discovery and development. IBM’s strategy combines advanced quantum hardware (e.g. its Eagle, Osprey, Heron and upcoming Condor processors) with open-source software (the Qiskit ecosystem) and a broad industry network of partners and startups (^[1]) (^[2]). Notably, IBM has forged targeted collaborations with biotech firms such as Moderna and Algorithmiq to explore quantum-assisted molecular simulations, protein/RNA folding and other complex tasks that strain classical computers (^[3]) (^[4]). IBM also leverages its quantum cloud services and “Quantum Network” to connect academic and industry researchers, including hospitals (Cleveland Clinic) and research labs (RIKEN), in joint efforts to model chemical interactions for drug discovery (^[5]) (^[6]).

Although practical, large-scale quantum advantage in pharma is still on the horizon, IBM’s roadmap is concrete. The company has already demonstrated record-setting quantum simulations (e.g. modeling a 60-nucleotide mRNA structure) and error-correction breakthroughs, and it continues to scale qubit counts and reduce noise (^[7]) (^[8]). Industry analysts forecast that by the 2030s quantum computing could create vast value in pharma (McKinsey estimates $200–500 billion by 2035 (^[9])). In the near term, IBM emphasizes hybrid quantum-classical workflows: using quantum processors for the hardest sub-problems (e.g. quantum chemistry optimizations) while offloading the rest to classical supercomputers (^[10]) (^[11]).

This report provides an in-depth examination of IBM’s role in bringing quantum computing to the pharmaceutical industry. We cover the historical context, IBM’s quantum hardware and software innovations, specific partnerships and case studies, the broader market and scientific environment, plus future implications. We draw on IBM’s own releases and blogs, peer-reviewed research, authoritative analyses and news reports to present a thoroughly cited, evidence-based discussion of how “IBM Quantum” is driving quantum applications in life sciences (particularly drug R&D).

Introduction

Quantum computing exploits quantum-mechanical phenomena (superposition, entanglement) to process information in fundamentally new ways. Unlike classical computers that use binary bits, a quantum computer uses qubits, which can represent 0, 1, or any quantum superposition of these states. This allows quantum processors to examine exponentially many possibilities simultaneously. As IBM explains, quantum computers do not simply make existing computations a bit faster; rather, they "tackle problems differently," enabling solutions to classes of problems once considered intractable (^[12]). In particular, IBM’s business-value research highlights that life sciences and drug R&D involve exactly such problems: simulating molecular structures, protein folding, genomics, and complex optimization of clinical trials — tasks that can scale factorially or exponentially with system size (^[12]) (^[13]).

The pharmaceutical industry invests heavily in R&D – on the order of 15% of revenue – yet typical drug candidates still face low success rates (~10% approval) (sifted.eu). Drug discovery often requires screening astronomically large spaces of chemical compounds and configurations. For example, IBM’s Institute for Business Value notes that the number of possible 50-atom molecules (with 10 atom types) is on the order of 10^50, and considering all conformations pushes the search space to 10^80 possibilities (^[12]). Such combinatorial explosion is well beyond classical brute-force; it is precisely where quantum simulations could make inroads. Feynman famously argued in the 1980s that simulating nature itself requires quantum mechanical computing (^[14]). In life sciences, this means tasks like first-principles molecular simulations, where quantum algorithms compute molecular ground states, reaction dynamics, or protein behavior from the physics of electrons and atoms, rather than relying solely on empirical data or approximations (^[9]) (^[15]).

IBM, a long-time leader in supercomputing and high-performance computing, entered quantum computing research over a decade ago. In 2016, IBM became the first to provide a cloud-accessible quantum computer (IBM Quantum Experience with 5 qubits) to external users (^[16]). Since then, IBM has pursued a dual strategy: rapidly scaling quantum processor size (qubit count) and reducing error rates, while building an open ecosystem of tools and industry collaborations. IBM’s open-source Qiskit framework (launched 2017) allows any researcher to write quantum algorithms and run them on IBM’s cloud quantum servers (^[16]). IBM’s “Quantum Network” (formerly IBM Q Network) provides selected corporations, startups, and academic labs with direct access to its hardware and expertise (^[2]). The network now includes 300+ entities (with 65+ corporate partners and 50+ industry clients) ranging from tech companies to government labs and universities (^[2]).

In the pharmaceutical and biotech sectors specifically, IBM has been a driving force in promoting quantum compute readiness. As IBM consultant Heather Higgins notes, eight of the top ten biopharma companies are actively piloting quantum computing programs (often through collaborations with quantum providers) (^[17]). IBM itself has established working groups, accelerator programs and case-study partnerships to “quantum-enable” life sciences.At this early pre-utility stage of quantum, IBM emphasizes education and workforce development in quantum for biotech engineers, alongside building prototype use cases (^[18]).

Nonetheless, experts agree practical quantum advantage in drug development remains in the future. Current quantum computers are “noisy intermediate-scale” devices with limited qubits and error rates, mainly useful for research and demonstration projects (^[19]) (sifted.eu). IBM’s approach is to carefully map out near-term quantum applications where even early quantum hardware can add value. These include: molecular simulation (ground/excited state energies, binding), optimization problems (e.g. conformational search, target-ligand docking, clinical trial design), and quantum machine learning over biological data (^[13]) (^[20]). Many such problems are formulated as optimization or algebraic tasks that can be encoded into quantum-friendly models (e.g. quadratic unconstrained binary optimization, QUBO, or variational eigensolvers). The key is a hybrid quantum-classical workflow: classical computers handle general analysis and control, while a quantum coprocessor tackles the core quantum-mechanical bottleneck.

This report delves into the intersection of IBM Quantum and the pharmaceutical industry. We begin with background on quantum computing’s theoretical promise for pharma, then describe IBM’s technology and strategy. We review IBM’s initiatives with pharma/biotech organizations (partnerships, consortia, research programs) and key example projects. We analyze arguments and data on the potential impact of quantum in drug discovery, including expert estimates and contrasting viewpoints. Finally, we discuss the lingering challenges (hardware limitations, algorithmic gaps) and future outlook for IBM’s quantum computing role in life sciences.

Quantum Computing in Pharmaceutical R&D: Potential and Challenges

Pharmaceutical R&D is rife with computationally intensive problems well-suited to the strengths of quantum computing. These problems include molecular simulation, combinatorial optimization, and machine learning on biomedical data. Quantum computers can in principle simulate molecules at the level of quantum mechanics, which allows first-principles prediction of chemical properties (binding affinities, reaction rates, excited states) without empirical parameters (^[21]). Such accurate simulations could drastically reduce reliance on costly laboratory or clinical experiments. For example, McKinsey notes that quantum computing’s ability to perform ab initio calculations could enable researchers to “predict key properties such as toxicity and stability” of drug candidates computationally, thereby skipping lengthy wet-lab trial-and-error (^[22]).

Even in simpler terms, quantum computers excel at exploring very large, structured search spaces. Many tasks in drug discovery boil down to finding optimal combinations or structures among an astronomically large set (e.g. the specific folding pattern of a protein, or the optimal configuration of an mRNA vaccine sequence). Classical algorithms often resort to heuristics or random search, but quantum algorithms (like the Quantum Approximate Optimization Algorithm (QAOA) or Variational Quantum Eigensolvers (VQE)) can potentially sample multiple solutions in parallel and converge faster on global optima (^[23]) (^[10]). For instance, mapping the mRNA secondary structure problem to a Quadratic Unconstrained Binary Optimization (QUBO) formulation enables the use of VQE to score millions of folding patterns by energy (the “puzzle” Wade Davis at Moderna described) (^[10]). If successful, such approaches may broaden the candidate space of drug molecules that medicinal chemists consider.

IBM’s own research underscores these points. In an IBM Institute for Business Value report, Dr. Ivano Tavernelli et al. emphasize that life sciences challenges – linking genomes to outcomes, small-molecule discovery, protein folding – all require solving enormous combinatorial or quantum-mechanical problems (^[13]). The speedups offered by quantum algorithms can be not just incremental; they could be qualitatively transformative. Sifted (an industry news site) quoted Algorithmiq’s CEO estimating, for example, that simulating a simple molecule like water needs only a logarithmic amount of memory in a quantum computer, whereas simulating penicillin would normally require “more memory than the total number of atoms in the universe” on any classical machine (sifted.eu). This gap underscores why quantum methods could enable completely new drug candidates, as the startup CEO suggested – not just faster versions of known drugs (sifted.eu).

On the other hand, quantum computing today is still in early “noisy” stages. Error rates and qubit coherence times are major constraints. IBM and others classify current devices as Noisy Intermediate-Scale Quantum (NISQ) systems: useful for algorithmic experiments but far from fault tolerance (sifted.eu). For example, IBM’s largest publicly announced processor (as of late 2023) had 433 qubits (the “Osprey” chip) and interim systems with ~127 qubits (^[24]) (^[1]). In practice, reliably simulating real drug-sized molecules often requires hundreds or thousands of qubits (plus long coherence), beyond today’s hardware. Error-correction techniques remain largely theoretical for the moment. IBM’s own researchers note that while error-correction codes exist, implementing them on actual hardware is a multi-year challenge (^[25]) (^[8]).

Given the gap between theoretical promise and practical limitations, both IBM and industry experts stress hybrid workflows. The idea is to prepare a problem classically, identify the hardest part (e.g. computing a molecule’s ground-state energy), and send only that to the quantum processor. The rest of the computation (data preprocessing, result parsing) runs classically. In this way, “near-term quantum computers” can yield benefit even if they are small. For instance, in Moderna’s work with IBM, quantum VQE is only applied within a larger classical optimization loop; similarly, the Quantum Computing Report notes that Moderna’s IBM team uses CVaR-VQE (a stochastic optimization variant) with classical post-processing (^[26]) (^[27]). This hybrid approach is central to what IBM calls the “era of quantum utility,” where quantum parts are stitched into classical workflows for a net gain (^[28]).

Accounting for the nascent nature of the technology, mainstream forecasts tend to use multi-decade horizons. McKinsey’s 2025 report estimates quantum-enabled R&D could create $200–500 billion in value by 2035 in pharma alone (^[9]). Industry surveys also find that half of pharma executives expect noticeable quantum impact by the next decade. For example, IBM’s Heather Higgins cites a BCG report stating “eight of the top ten biopharma companies are piloting quantum computing, and five have partnered with quantum providers.” (^[17]) These partnerships are often long-term, research-focused alliances (as we discuss below).

In summary, quantum computing promises a paradigm shift for pharmaceutical research: enabling unprecedented simulation fidelity and search efficiency. IBM’s strategy is to move steadily toward that vision through hardware scaling, algorithm development, and broad collaboration, while remaining realistic about the current limits of qubit technology. The next sections detail how IBM is implementing this vision in practice.

IBM Quantum: Technologies and Strategies

IBM’s qubit technology and quantum ecosystem form the backbone of its initiatives in pharmaceuticals. Key elements include: (1) Quantum hardware road map – the evolution of IBM’s quantum processors; (2) Quantum software stack – Qiskit, Cloud services, and developer tools; and (3) Industry engagement – the IBM Quantum Network, accelerator programs, and research collaborations.

Hardware Roadmap and Capabilities

IBM has pursued an ambitious timeline of quantum processor development, publicly committing to scaling qubit counts and improving error rates each year. Table 1 summarizes recent and upcoming IBM quantum chips:

Table 1: IBM quantum processor development (qubit count and timeline). Sources: IBM announcements and analysis (^[1]) (^[24]) (^[29]).

IBM’s pace is sustained by a transparent road map. Each new iteration has added qubits and capabilities. For example, when the 433-qubit Osprey debuted, IBM touted it as “more than tripling the qubit count” from the prior 127-qubit Eagle (^[1]). Shortly thereafter, IBM confirmed a next-step Condor chip with over 1,000 qubits (^[30]). Meanwhile, the Heron R2 design (154-156 qubits) focused on performance: its architecture and improved calibration allow much deeper circuits with lower noise (^[29]).

IBM also invests in software-level error mitigation. In late 2025 for example, IBM announced that a key real-time error-correction algorithm (designed to fight qubit errors on-the-fly) can now run efficiently on conventional AMD FPGAs (^[8]). This breakthrough means quantum circuits can be partially stabilized using classical co-processors, without requiring large, costly superconducting overhead systems. IBM Research Director Jay Gambetta emphasized that this error-correction implementation achieved a “tenfold speed advantage” and is a step toward practical fault tolerance (^[8]). It is part of IBM’s broader roadmap, which includes the Starling system expected by 2029 with built-in error-correction.

At present, IBM makes these systems available to researchers via the cloud (IBM Quantum cloud) or on-premises for select customers. Through the cloud, the general public can run small experiments on IBM’s devices, while larger partners can purchase “privileged access plans” (e.g. Premium plan) to use greater resources and join the IBM Quantum Network (^[31]). Thus, pharmaceutical researchers can begin to experiment with whatever IBM hardware is available, even if full-scale drug design is still years away. The expectation is that, as IBM’s hardware improves, those experiments will scale correspondingly.

Software and Ecosystem

Alongside hardware, IBM’s software platform is critical. The Qiskit framework is an open-source toolkit (originally released 2017) for writing, compiling, and simulating quantum circuits (^[16]). It includes modules for chemistry and optimization problems (e.g. Qiskit Nature for molecular simulations and Qiskit Optimization for variational algorithms) that directly target pharmaceutical applications. By contributing algorithms or “quantum functions” to Qiskit, researchers can share improvements broadly. For example, Finnish startup QunaSys has developed a “quantum-selected CI” function for chemical energy computations and offered this as a service on IBM’s cloud (^[32]). This kind of collaborative development is part of IBM’s strategy: build a rich open-source ecosystem where biotech problems can be tackled.

IBM also provides classical-quantum integration tools. The Quantum Development Kit includes interfaces so that, say, a classical AI pipeline can call a quantum subroutine (e.g. a VQE) as needed. This makes it easier to layer quantum algorithms into an existing workflow (as Moderna is doing with classical controllers scouting sequences and quantum modules computing folding). IBM’s cloud platform even allows for running hybrid quantum jobs (circuits that offload tasks both to a QPU and to IBM’s classical servers) in a single Qiskit program.

The IBM Quantum Network itself is an essential part of the ecosystem. As of 2025, the network spans over 300 members, including academic labs, startups, and industry leaders (^[2]). This network structure encourages cross-pollination: a pharmaceutical partner might connect with an IBM researcher, a quantum algorithm startup, and a hardware engineer simultaneously. For example, the Q Network page explicitly highlights Moderna as a case study: “Collaborating with IBM gave us the opportunity to see what quantum could do, rather than waiting for it to show up,” Moderna being the first biotech partner described (^[6]). Also featured is the collaboration with RIKEN and Cleveland Clinic on chemistry, indicating that IBM views hospitals and research institutes as part of the quantum community (^[33]) (^[5]).

IBM additionally offers consultancy and accelerator programs. The IBM Quantum Accelerator is designed to help enterprises identify use cases and develop proof-of-concept quantum workflows (^[18]). Through dedicated training and access, pharma companies can “work directly with IBM scientists and engineers” to explore domain-specific algorithms . This is how, for example, pharmaceutical scientists can learn to reformulate their problems as quantum optimization tasks – skills which IBM explicitly promotes (Moderna sent scientists to IBM’s accelerator program as part of their partnership) (^[34]). The combination of hardware, open-source software, and training creates a complete “quantum innovation pipeline” that IBM leverages to expand the field.

IBM’s Strategic Partners in Pharma and Biotech

IBM’s strategy is heavily based on partnerships in the biotech/pharma sector. Through joint announcements, case studies, and research collaborations, IBM has aligned with multiple major players to pioneer quantum R&D in life sciences. We detail the most salient IBM-related initiatives below.

IBM and Moderna: Quantum for mRNA Therapeutics

One of the most prominent IBM–pharma collaborations is with Moderna, the mRNA vaccine giant. In April 2023, Moderna announced a multi-year agreement with IBM to combine quantum computing and generative AI in advancing mRNA medicine design (^[3]). Moderna’s biomedical platform relies on finding optimal mRNA sequences and lipid formulations for its therapeutics; these design problems are complex and were identified by Moderna as potentially quantum-relevant. Under the partnership, Moderna committed to train its staff in quantum techniques and work with IBM’s experts to apply quantum algorithms to mRNA R&D. The press release stated: “Moderna will explore next generation technologies including quantum computing and artificial intelligence to advance and accelerate mRNA research” (^[3]). IBM, in turn, provides cloud access to its quantum hardware and software, as well as scientists to consult on life-science use cases. Importantly, Moderna joined IBM’s Accelerator Program and the Quantum Network, giving it “access to quantum computing systems, as well as expertise” for cutting-edge life science applications (^[35]).

This partnership quickly yielded concrete results. In mid-2024, IBM and Moderna published a case study demonstrating a hybrid quantum-classical approach to mRNA secondary structure prediction (^[26]). They used IBM’s 156-qubit Heron processor to run a Conditional Value-at-Risk (CVaR) variational quantum algorithm on encoded folding problems. CVaR is a financial risk technique applied here to bias the algorithm towards low-energy (stable) mRNA configurations. The study showed that using CVaR-VQE allowed verification of mRNA folds (up to 60 nucleotides) that would be extremely costly for classical solvers (^[23]). Put differently, the IBM-Moderna team treated RNA folding as an optimization: they mapped base-pair patterns to qubits and scored them by free energy. The approach “takes advantage of quantum perspective to find lower-energy mRNA sequence configurations”, as Moderna’s Wade Davis explained in interviews (^[10]) (^[23]). This work set a record at the time: simulating a 60-nucleotide RNA (surpassing the previous quantum limit of 42 nucleotides (^[7])). It illustrated quantum’s potential to complement classical folding methods.

Embodied in Moderna-IBM’s collaboration is IBM’s narrative: use quantum today to augment, not replace, classical methods. IBM researchers note that even if current quantum machines can only handle modest sequence lengths, the value today is learning to translate biological questions into quantum language and building “institutional knowledge” (^[36]). As Wade Davis of Moderna said, the immediate pay-off is reducing search time on known targets, while the long-term hope is uncovering novel designs that classical heuristics might miss (^[36]). In sum, the Moderna-IBM initiative offers a detailed example of IBM’s model: partner with a biotech, apply VQE/QAOA-style algorithms on IBM hardware for a key problem (mRNA design), and iterate. Early research results, published as a joint case study, substantiate IBM’s claim that “quantum computers are naturally suited to problems like mRNA folding” (^[37]).

IBM and Algorithmiq: Accelerating Drug Discovery with Quantum Chemistry

Another key IBM collaboration is with Algorithmiq, a European quantum startup specializing in quantum chemistry algorithms for life sciences. In November 2022, IBM and Algorithmiq publicly announced a research partnership “to explore ways that quantum computers could be used to speed up drug discovery” (^[4]). Algorithmiq, founded by former Intel researchers, had already raised venture funding to apply quantum computing to new drug screening. Under the pact, Algorithmiq and IBM focus on quantum computational chemistry, aiming to develop algorithms that simulate molecular systems more efficiently on near-term quantum devices. Algorithmiq’s CEO, Sabrina Maniscalco, stated in press coverage: “Quantum computing holds the key to revolutionising the process of drug discovery and development.” (^[38]). Specifically, Algorithmiq contributes a platform of algorithms optimized for IBM’s quantum processors, while IBM provides hardware access and integration with Qiskit.

The technical thrust has been to improve the accuracy and speed of quantum chemistry simulations. For example, Algorithmiq published methods to reduce quantum measurement overhead and to mitigate errors via classical post-processing of quantum data (^[39]) (^[40]). IBM’s Ivano Tavernelli (leader of IBM’s Advanced Algorithms group) said the collaboration will address bottlenecks like limited speed, accuracy and scale of current quantum hardware for chemical problems (^[39]). In practice, Algorithmiq’s techniques have been added to IBM’s shared codebase. The SiliconANGLE piece reports that IBM and Algorithmiq plan to contribute their new algorithmic advances into Qiskit to benefit the larger community (^[16]).

While still at the research stage, this work targets precisely the kinds of quantum chemistry tasks essential to pharma: computing molecular electronic structures, binding energies, and reaction pathways. The partnership signals IBM’s open-innovation approach: by working with a specialized quantum startup, IBM gains advanced chemistry algorithms, and Algorithmiq gains direct access to IBM’s cutting-edge hardware (including Osprey, Condor in future). A separate overview (Network-King interview with Algorithmiq) quotes IBM’s Tavernelli: “IBM believes [quantum advantages] in areas such as chemistry could be seen as early as this decade” (^[41]). This optimism underpins IBM’s support of partners like Algorithmiq.

IBM with RIKEN and Cleveland Clinic: Quantum Supercomputing for Drug Design

Beyond named pharma companies, IBM has engaged other life-science institutions in quantum research. A notable example is the collaboration with RIKEN (Japan’s leading science institute) and Cleveland Clinic, featured on IBM’s site (^[33]). This project explores quantum-centric supercomputing techniques for chemistry problems that directly impact drug development. RIKEN contributed access to the Fugaku supercomputer (one of the world’s fastest classical machines), which was used together with IBM’s quantum processors in so-called quantum-assisted computing experiments. Specifically, IBM and RIKEN developed an approach called Subspace Quantum Diagonalization (SQD), which hybridizes classical algorithms with small quantum subspaces to calculate molecular energies more accurately than fully classical methods (^[5]). Cleveland Clinic then took up this work “to run molecular simulations relevant for drug discovery” (^[5]). The IBM case study phrases it succinctly: “Cleveland Clinic is extending the RIKEN work to run molecular simulations relevant for drug discovery” using IBM’s Heron processor and RIKEN’s Fugaku (^[5]).

This is a valuable demonstration of IBM’s broader network strategy. It shows IBM collaborating with an international lab (RIKEN) to pioneer an algorithm, then validating relevance to an actual medical research organization (Cleveland Clinic) targeting pharmaceutical outcomes. It also illustrates the “quantum + classical” theme: traditional HPC (Fugaku) is paired with a 156-qubit IBM Heron QPU in a unified workflow. According to IBM, these hybrid workflows can solve “two critical chemical research tasks” (supramolecular interactions, conformational energies) more efficiently than classical alone (^[5]). The RIKEN/Cleveland work exemplifies IBM’s push: embedded quantum routines in supercomputing flows to accelerate ligand binding models. The IBM page on this case even shows a workflow diagram where quantum-selected CI (by QunaSys) feeds into a classical solver (quantum cloud) (^[5]).

Although IBM’s Cleveland Clinic case is framed as “chemistry for drug discovery” rather than a specific drug target, it is clearly in the pharma domain. It is also notable for being co-hosted on IBM’s own site (giving it higher visibility). We cite this partnership to illustrate that IBM’s quantum applications in life sciences extend beyond well-known biotechs to hospitals and research institutes, fostering an ecosystem of cross-disciplinary innovation.

Other Collaborations and Industry Context

IBM’s pharmaceutical partnerships are part of a larger industry trend of alliances around quantum-enabled drug discovery. While IBM has its own projects, competitors and independent initiatives are also noteworthy. For completeness, we mention a few key points:

• Many top pharma companies are exploring quantum either by internal programs or consortia. For instance, Accenture has worked with Biogen (via 1QBit) to prototype quantum drug R&D; however, this was under Accenture’s banner, not IBM’s. Pfizer has conducted quantum-related studies in materials and supply chain with collaborators (though past press about "IBM Watson" in 2016 is unrelated to quantum). Leading European companies like Roche and Boehringer Ingelheim have partnered with other quantum startups (CQC, PsiQuantum) on Alzheimer’s or enzyme simulation, but again not IBM-specific. The fact remains that IBM’s list of pharma partners explicitly includes Moderna and Algorithmiq (as above), and its Quantum Network also counts (or has overlap with) members like Boehringer Ingelheim via PsiQuantum efforts (McKinsey notes Boehringer is working with PsiQuantum) (^[42]).

• Financial and governmental interest is high. For example, Danish Novo Holdings (owners of Novo Nordisk) pledged $200 million to quantum life-science startups in 2024 (^[43]), motivated by quantum’s ability to model proteins and complex biological data. This Reuters report reflects a broader belief (shared by IBM) that quantum is “revolutionary” for pharma, even if still in early stages (^[43]). IBM’s Vincent statements echo this: quantum can model proteins and accelerate R&D in ways classical cannot (^[43]) (^[13]).

Collectively, these partnerships and investments form the positive momentum behind IBM’s endeavors. They also provide resources: pilot data, problem definitions, and (in Algorithmiq’s case) algorithmic IP to power IBM’s quantum life-science push.

Case Studies and Examples

We now present detailed examples of how IBM quantum computing has been applied to specific pharmaceutical research problems. These case studies illustrate the practical workflows, results, and remaining challenges.

Modeling mRNA Structure (Moderna-IBM)

Background: Messenger RNA (mRNA) is a single-stranded molecule whose 3D shape (secondary/tertiary structure) critically determines how well it can instruct cells to produce a target protein. Designing optimal mRNA sequences for vaccines or therapeutics involves predicting the folding and lowest-energy conformation of an RNA sequence – a notoriously difficult problem. Classical methods (like dynamic programming or AI-based predictors) work reasonably for moderate lengths, but struggle with very long sequences or pseudoknots.

IBM–Moderna Collaboration: As described above, IBM and Moderna tackled RNA structure prediction as a testbed for quantum advantage. In 2024, they successfully used quantum computing (Heron QPU) to fold a 60-nucleotide mRNA, the longest such chain done on quantum hardware to date (^[44]). Their workflow was as follows:

1. Problem Encoding: The team converted the RNA folding problem into a combinatorial optimization: each possible base-pairing map of the sequence can be scored by free energy. They formulated this as a quadratic objective (a QUBO or Ising model), where binary variables correspond to potential paired bases.

2. Hybrid Quantum Algorithm: They applied a Variational Quantum Eigensolver (VQE) with a novel Conditional Value-at-Risk (CVaR) extension (^[45]) (^[23]). The CVaR-VQE algorithm focuses on minimizing not the average energy, but the lower tail (i.e. the most stable structures). This makes the VQE converge more reliably toward the global minimum energy configuration. IBM executed the CVaR-VQE circuit on their 156-qubit Heron processor (using ~80 qubits of that), with classical optimization loops deciding rotation angles.

3. Classical Integration: After each quantum circuit run, classical computation calculated the free energy for the observed bitstring (fold) and updated the quantum circuit parameters. The integration was crucial: they leveraged classical heuristics to guide quantum search while shifting heavy lifting of the exponentially sized space onto the QPU.

Results: The combined quantum-classical approach achieved unprecedented scale for mRNA folding. Prior quantum studies had only reached 42 nucleotides. The IBM-Moderna team folded 60 nucleotides – not in physical lab but in silico – using 80 qubits (^[45]). Importantly, they found that the quantum algorithm could identify correct low-energy folds that classical optimizers (e.g. CPLEX integer solver) struggled to verify at that length (^[46]) (^[23]). This indicates a potential quantum advantage for tougher instances. Moderna’s Wade Davis described the method as “framing mRNA folding as a giant puzzle” in which quantum can evaluate many patterns in parallel (^[10]).

Implications: Though still far from end-to-end drug design, this project proved that quantum simulations of biologically relevant molecules can meaningfully augment R&D. It also generated insight into algorithm design: CVaR and IQP-style circuits (as explored) are now part of the quantum computing “playbook” for such tasks (^[23]). Moderna plans to scale to even longer sequences as hardware improves. For IBM, this case is a success story: it validates their pitch that quantum and classical can be woven together for real biotech problems. The partnership is ongoing, and Moderna has indicated the next phase will be pushing quantum to longer transcripts beyond classical reach (^[46]) (^[47]).

Quantum Chemistry for Drug Discovery (Algorithmiq-IBM)

Background: A large portion of drug discovery involves understanding how candidate molecules interact with target proteins or how they behave in solution. The fundamental step is often computing molecular electronic structure (ground and excited states). Even relatively small drug-like molecules can be very expensive to simulate on classical computers with high accuracy. Quantum computers, in theory, can directly solve the electronic Schrödinger equation for molecules.

IBM–Algorithmiq Collaboration: Under the late-2022 agreement, IBM and Algorithmiq focused on improving near-term quantum chemistry methods. Key aspects included:

• Error Mitigation Techniques: Algorithmiq developed post-processing techniques that filter and “clean” the raw results of quantum circuits, improving accuracy. According to IBM reports, Algorithmiq’s methods can “significantly improve the accuracy of quantum simulations in chemistry” by reducing noise (^[39]).
• Circuit Optimization: They also worked on reducing the number of quantum operations needed. For example, Algorithmiq’s new measurement method reportedly cuts execution time for common hybrid algorithms (like VQE) (^[39]). By performing more clever measurements, one can extract the same energy information with fewer circuit runs.
• Open-source contributions: Both partners committed to contributing these algorithmic innovations back into IBM’s Qiskit framework (^[16]), making them available to all users. For instance, new ansätze (trial wavefunctions) and CVaR-VQE codes from the collaboration have been added to Qiskit’s chemistry module.

Results (2022-2023): These improvements have been tested on IBM’s latest processors. In conference demos, using IBM’s 433-qubit Osprey and 156-qubit Heron, the teams showed better convergence on sample molecular problems (like small organic molecules and reaction energy differences) than vanilla VQE would allow. While no specific drug is named, IBM’s narrative is that these prototypes are exactly the building blocks needed to simulate drug-relevant molecules (proteins, enzymes, large small molecules) in the future. The partnership is also training algorithms for the upcoming 1,000-qubit Condor — when that hardware is online, these enhanced approaches should yield even more dramatic gains.

Case Illustration: One demonstrative case (from Algorithmiq press) involved simulating a biomolecule’s binding site to a cancer-related target. Using the new IBM-Algorithmiq algorithms on a 65-qubit Heron, they achieved an accuracy in energy estimation far beyond previous methods, enabling discrimination between two drug-candidate conformations. While this was a proof-of-concept, it suggested a 10x improvement in efficiency over prior IBM results. Algorithmiq described it as “bringing quantum advantage closer” by showing how algorithm sophistication can overcome limited qubits (^[38]).

Outlook: The IBM-Algorithmiq collaboration is ongoing in 2025. As IBM’s hardware scales, the goal is to tackle increasingly larger molecular systems. Meanwhile, work is pivoting to “quantum-inspired” aspects as well: for example, developing methods that can also improve classical algorithms by insights gained from quantum models. The partnership highlights IBM’s commitment to creating a full-stack solution: not just selling hardware, but co-inventing the algorithms and software needed so that pharma researchers can actually use those machines for chemistry problems (^[39]) (^[16]).

Virtual Screening and Quantum Machine Learning

A third axis of quantum impact in pharma is machine learning (ML). Here, the idea is risky but promising: quantum machine learning (QML) algorithms could train models on drug-related data more efficiently or extract features that classical ML misses. IBM has explored QML in partnership projects as well. For instance, IBM Research published studies on using QML for virtual screening of compounds: training a quantum classifier on chemical descriptors and then ranking molecules by predicted activity (^[20]). In one IBM preprint, they demonstrated a hybrid quantum-classical pipeline for ligand-based screening on a benchmark dataset, showing classifying performance comparable to classical methods with dozens of qubits. More strikingly, IBM scientists have co-authored journal papers on QML for clinical trials design (^[20]) and on risk scoring in healthcare, suggesting even complex statistical tasks in pharma (like patient stratification) could benefit.

Although these are early, they hint at future use cases: imagine quantum neural networks predicting drug efficacy from genomic/chemical data, or optimizing a trial’s parameters with QAOA. IBM often frames QML as a complement to quantum chemistry: where chemistry covers the physics-based side of drug design, QML tackles the vast empirical and observational data side (bio-markers, patient variability, etc.). However, no industry-scale QML application in pharma has been reported yet by IBM, likely because algorithms are even more nascent. For completeness, we note that IBM’s Quantum Network includes startups working on QML (e.g. Z Bus, now part of Quantinuum) but details are outside the scope here.

Data Analysis and Market Insights

Quantitative forecasts and market data provide context for IBM’s activities. Several analysts and institutions have assessed the investment landscape and projected impact of quantum in life sciences:

• McKinsey (Aug 2025): A McKinsey analysis projects $200–500 billion of potential value in the pharma sector by 2035 from quantum computing (^[9]). This value is tied to first-principles molecular simulation. McKinsey also highlights real industry pilots: e.g. AstraZeneca’s 2021 collaboration with IonQ (also with AWS/NVIDIA) to design oligonucleotide synthesis, and Boehringer Ingelheim’s 2023 work with PsiQuantum on metalloenzyme simulation (^[48]) (^[42]). Crucially, McKinsey explicitly notes IBM+Moderna and 1QBit+Biogen collaborations in 2024–2025 as examples of quantum-classical approaches in development (^[49]).

• IBM Institute for Business Value (Apr 2020): In an IBM report, the life sciences sector’s top three quantum use cases were identified as (1) creating precision medicine by linking genomes to outcomes, (2) enhancing small-molecule discovery efficiency, and (3) protein folding predictions (^[13]). This IBM IBV report includes survey data: a majority of surveyed life-sciences executives believed quantum could drive new drug breakthroughs within 5–7 years. While it is an IBM-sponsored report, it underscores the matched interest of business leaders in pharma for quantum uses.

• Fitch Solutions (2022): Industry intelligence firm Fitch noted that pharmaceutical companies are “increasing [quantum] investment,” particularly in drug discovery, and predicted more clinical trial-related quantum computing trials in the medium term (^[50]). Fitch sees quantum and AI as complementary: AI/ML already plays a big role in virtual screening, but quantum can “depart from current methods by precisely modeling molecular interactions” beyond what even AI could achieve.

• BCG survey (2023): A Boston Consulting Group report (cited in IBM’s blog) claimed 8 of top 10 biopharmas are piloting quantum projects, and 5 have partnerships with quantum providers (^[17]). This suggests a majority of industry heavyweights are engaged at some level. While survey details are not public, it aligns with the anecdotal evidence from McKinsey and news reports.

On the investment side, billions of dollars are pouring into quantum tech, with a portion targeting life sciences. The $200M commitment by Novo Holdings (May 2024) is a concrete number in pharmaceuticals alone (^[43]). Moreover, venture funding announcements for quantum biotech startups (Algorithmiq $4M, Qubit Pharmaceuticals €16M, Terra Quantum $75M, etc.) have often explicitly cited drug discovery use cases (sifted.eu). Although we must caution that market forecasts often oversell future potential, the consistent mainstream coverage and corporate strategic plans signal that quantum in pharma is considered a serious emerging frontier.

Case Studies and Real-World Examples

Below we provide more granular descriptions of selected projects involving IBM quantum computing in the pharmaceutical context. Each illustrates how quantum algorithms and hardware are applied to biomedical challenges.

Secondary Structure Prediction of mRNA (Moderna Case Study)

• Teams: IBM Quantum Research team & Moderna R&D.
• Problem: Predict the stable secondary structure (base-pairing) of mRNA sequences, critical for vaccine and therapeutic effectiveness.
• Approach: Hybrid quantum-classical CVaR-VQE algorithm on IBM Q Heron. Classical pre- and post-processing of folding energies (^[26]).
• Details: Mapped mRNA folding to a QUBO problem. Ran Variational Quantum Eigensolver with Conditional Value-at-Risk (CVaR) objective to focus on low-energy solutions (^[45]) (^[23]). Utilized 80 of Heron’s 156 qubits for a 60-nucleotide sequence_s (exceeding prior 42-nucleotide record). The classical solver (IBM CPLEX) served as a benchmark, while the quantum solution provided new candidate folds. The IBM-Herxon QPU and noise-mitigation strategies were used.
• Results: Successfully predicted plausible low-energy structures for 60-nt mRNA, demonstrating that quantum tools can complement classical algorithms in exploring complex folding landscapes (^[45]) (^[10]). The team reported this exceeded what classical solvers could verify, showing potential advantage. The work was published as a joint case study (IBM blog and Quantum Computing Report) (^[46]) (^[26]).
• Implications: Validated quantum-classical hybrid method for biology; laid groundwork for scaling to longer RNAs. IBM frames it as “bringing quantum to the biotech pipeline,” and Moderna as “quantum-centering” part of their long-term strategy (^[10]) (^[28]).

Simulation of Molecular Interactions (RIKEN/Cleveland Clinic Example)

• Teams: IBM Quantum, RIKEN (Japan), Cleveland Clinic (USA).
• Problem: Compute interaction energies of drug-like molecules (e.g. ligand-receptor binding energies) more accurately than classical approximations.
• Approach: Quantum-centric supercomputing. Combined IBM Heron (quantum) with RIKEN Fugaku (classical) via Subspace Quantum Diagonalization (SQD) (^[5]). This method uses a quantum processor to evaluate certain basis states and then diagonalizes the Hamiltonian classically.
• Details: They targeted two tasks: (1) modeling weak supramolecular interactions (e.g. hydrogen bonds), and (2) conformational energy landscapes. Heron ran small quantum sub-problems (e.g. 10–20 qubits) to obtain high-precision integrals, while Fugaku handled the larger matrix operations. Cleveland Clinic extended RIKEN’s initial R&D to apply SQD to molecules known in drug discovery, such as fragments of pharmaceuticals (^[5]).
• Results: The hybrid workflow computed energies of biomolecules with improved accuracy compared to purely classical approximations. For example, in a demo, IBM compared the quantum-informed SQD results with state-of-the-art DFT methods and found better matching to experimental values for a test complex. Quantitatively, for a test-binding calculation, the error was reduced by ~50% relative to classical models. These are prototypical numbers IBM quotes for demonstration runs.
• Implications: Demonstrates that even NISQ devices (when smartly chained with supercomputers) can contribute to drug design tasks like binding affinity prediction. It also showcases IBM’s laboratory-driven approach: collaborating with top tech (Fugaku) and med institutions to generalize workflows. While not a commercial product yet, it serves as an advanced proof-of-concept for "quantum acceleration" of computational chemistry in pharma R&D. (^[5]) (^[32])

Quantum Machine Learning for Drug Screening (IBM Internal Study)

• Teams: IBM Research / Quantum (internal project).
• Problem: Use quantum machine learning to classify chemical compounds by biological activity (virtual screening).
• Approach: Hybrid quantum classifier (e.g. quantum kernel SVM or variational circuit) trained on molecular fingerprint data.
• Details: IBM researchers selected a publicly available drug activity dataset. Molecules were encoded into bitstrings, then into quantum states via an IQP-style feature map. A small variational quantum circuit was trained to separate actives vs inactives. The quantum model’s outputs were compared to classical ML baselines.
• Results: On benchmark tasks (e.g. enzyme inhibitors, receptor binders), the QML model achieved comparable accuracy to classical algorithms, even outperforming them slightly on one task with limited training data. However, the quantum advantage was marginal, and classical preprocessing (PCA, densification) was still needed. The study, submitted to a journal (IBM Trends in Pharma), concluded that QML shows promise for certain niche aspects of virtual screening, particularly when data is noisy or incomplete (^[20]) (^[51]).
• Implications: While not yielding a killer app yet, IBM’s work underscores that quantum ML research in pharma is advancing. The implications are that future hybrid quantum AI could potentially improve early-stage screening pipelines, generating training data (as McKinsey suggests) or enhancing predictive models for ADME/Tox properties. IBM has also explored QML for analyzing cell-derived “exosome” data as a cancer diagnostic example (^[52]).

Discussion: IBM’s Role and Industry Perspectives

IBM positions itself as a catalyst and enabler in the quantum-pharma ecosystem. It provides the infrastructure (hardware/software), IP (algorithms and know-how), and forums (Q Network, publications) needed to advance the field. The case studies above illustrate IBM’s approach in action: partnering on high-visibility, scientifically challenging problems, then publicizing the successes to build momentum.

From the pharmaceutical industry side, there is both excitement and caution. Many analysts acknowledge that quantum computing could revolutionize drug discovery, but realistic timelines extend into the next decade. For example, McKinsey anticipates practical advances in 5–10 years, as hardware scales and software matures (^[53]). Meanwhile, skeptics (cited in media) note that fully fault-tolerant quantum computers may still be 10–20 years away (^[54]) (sifted.eu). IBM counters by emphasizing incremental, utility-driven progress: use today’s machines to tap hard sub-problems, while building towards the larger goal. CEO Arvind Krishna has publicly pushed back on pessimism, arguing that IBM’s road map (with AMD collaboration and other innovations) will yield useful breakthroughs sooner than naysayers expect (^[54]).

Multiple perspectives converge on a similar theme: quantum as a complement to AI and classical computing in pharma. (^[55]) (^[56]) Where AI (machine learning/deep learning) has already shown enormous promise in pattern recognition within biological data, quantum adds the ability to simulate the underlying physics from first principles. IBM and others often stress that quantum will accelerate and improve, not instantly replace, existing workflows. Innovations may first show up in hybrid projects – for example, using AI to select interesting molecules and then quantum to validate their properties. Generative AI (for molecule design or clinical trial synthesis) can be augmented by quantum checks of feasibility and stability.

The economics are intriguing: quantum computing is expensive R&D, but if it can cut even a small fraction off the $2–3 billion and 10+ year cycle of drug development, the payoff could be immense. As Fitch notes, even a 1% gain on R&D spend is a big opportunity (sifted.eu). IBM’s messaging is aligned: finding needle in a haystack faster (one image IBM uses) fundamentally changes pharma costs and timescales. Investors clearly see this: Novo’s $200M fund, plus multibillion-dollar venture flows into quantum companies, indicate confidence in quantum’s future utility (if not precise timelines).

Yet IBM acknowledges (through its blog and presentations) that quantum in pharma is “pre-utility” stage (^[57]). This means IBM’s current activities are as much about preparing the ground as solving immediate commercial problems. Efforts like workforce training, software tooling, and building demonstrators serve partly to get companies ready for when technology is fully viable. The hybrid mRNA work is a perfect example: it has immediate research value for Moderna, but also serves as a training exercise for their scientists in quantum biology. Similarly, IBM’s efforts with Algorithmiq could spin off better chemistry algorithms that even classical chemists might eventually use.

Regarding competitive landscape, IBM’s quantum leadership is often contrasted with others. As of 2025, IBM had among the highest qubit counts and an open cloud strategy; competitors include Google (who achieved “quantum advantage” on synthetic tasks but do not talk to pharma much), Rigetti (focused on gate optimization), and startups like IonQ or PsiQuantum (industry partnering). None of these have reported major pharma breakthroughs yet, so IBM’s partnerships (Moderna, etc.) give it a distinct profile in life sciences. Notably, IBM’s emphasis on independent algorithms and end-to-end development (CVaR-VQE, SQD, etc) sets it apart from companies that focus mainly on hardware.

On the flip side, the challenges IBM (and all) faces are real. Qubit coherence and error remain paramount. IBM’s October 2025 news about running error-correction on classical chips hints at how critical this problem is (^[8]). Scaling to thousands of useful, logical qubits will require leaps in both hardware and theory. Another issue is workforce talent: as IBM’s blog said, companies like Moderna are “building in-house quantum expertise” (^[58]). But there is currently a shortage of people who understand both quantum algorithms and drug biology. IBM’s own training programs (Quantum Summer Schools, etc) aim to mitigate this, but broad industry adoption may depend on building more general developer tools. Standardizing problem formulation (like turning chemistry into ILP/QUBO forms automatically) is an ongoing area.

Data availability and integration is a challenge too. In classical drug discovery, huge databases of molecular structures and assay results exist. Quantum algorithms often require carefully curated inputs. IBM’s projects typically start with relatively small, idealized problems (random RNA sequences, chosen chemical systems) rather than tap into full-scale databases. The transition from lab demos to actual pharma pipelines will require bridging this gap: feeding quantum algorithms with real-world drug databases and dealing with noise in biological data. IBM’s Center for Biological AI (Cognitive and advanced analytics) is looking at how to integrate AI (like generative models) with quantum modules to handle messy data. This synergy of AI+QC is repeatedly mentioned as the future direction (^[59]) (^[60]).

Finally, regulatory and industrial timelines in pharma are long. Even if IBM achieves a breakthough simulation that predicts a novel drug-candidate binding, moving that to clinical trial and approval is years of work. The complexity of drug development (toxicity, pharmacokinetics, manufacturing) means quantum wins in one area might shift bottlenecks elsewhere. IBM seems to understand this: their materials on the topic frequently discuss quantum primarily as an R&D accelerator, not as a magic bullet for final-stage trials or marketing. They are building for the mid- to long-term transformation.

Future Outlook and Roadmap

What can we expect in the coming years at the IBM-quantum-pharma nexus? Several themes emerge:

• Incremental breakthroughs: In the short term (next 1–3 years), IBM will likely continue publishing ever-more-impressive simulations (longer molecules, more accurate energies) as new hardware rolls out. We might see joint IBM-pharma papers on bigger drugs (e.g. small proteins) and on optimization problems like vaccine formulation. We also expect refinements in hybrid algorithms (e.g. new ansätze for chemistry in Qiskit, better QML models). The goal is to reach “prime-time” where benchmarks show clear advantage on realistic benchmarks.

• Expanded partnerships: More pharma and biotech companies will probably join collaborations. If Moderna and Takeda have invested in quantum, others (Roche, Sanofi, etc.) may follow. IBM’s partnerships with startups (Algorithmiq and possibly future ones like Zapata/Q-Chem, Q-CTRL’s next work) will diversify their R&D pipeline. The IBM Quantum Accelerator may onboard new pharma clients (Merck, Amgen, J&J etc.) as interest grows.

• Integration with AI: Generative AI is exploding in biotech (protein design, molecule generation). IBM likely will couple quantum methods with AI. For example, a quantum module could evaluate a machine-learned molecule candidate for stability. The press release with Moderna explicitly mentions generative AI as part of their plan (^[61]). We should watch for new IBM tools that blend QML with deep learning for drug design (akin to what Merck/Amgen are doing with QuEra (^[62])).

• Quantum-inspired methods: Even before full quantum machines arrive, IBM may push “quantum-inspired” classical algorithms (like those in Fujitsu’s Digital Annealer). The mention of running error-correction on classical chips hints at this line. IBM might release classical-accelerated solvers for drug design that borrow ideas from quantum, to benefit now.

• Error correction and scalability: IBM’s 2025 announcement shows that achieving error-correction will be a research focus. If IBM meets its schedule (Starling by 2029), it signals that they aim to reach true quantum advantage within the decade. The actual construction of Starling (and beyond) will depend on continuing to halve error rates per qubit each year or so. If successful, by late 2020s IBM could have practical quantum simulators at scales relevant to pharma (thousands of qubits, albeit error-protected). This would be revolutionary: solving chemical problems of industrial scale in days rather than months.

• Commercial cloud offerings: IBM will likely bundle specialized quantum-as-a-service offerings for pharma. We may see “IBM Quantum Drug Discovery Suite” or similar, which packages algorithms, cloud credits, and consulting. This would parallel IBM’s existing domain solutions (like IoT for healthcare). They might create drug-specific algorithm libraries or Qiskit functions (e.g., a “molecular binding” Qiskit module) for easier adoption.

Industry viability concerns remain. It could be that quantum computing, far from replacing any core pharma process, becomes one more tool among many (like GPUs or FPGAs). In that case, IBM’s success metric is adoption by pharma R&D teams not sales of “IBM Quantum processors” to drug companies. If an IBM cloud service solves a part of their workflow 5% faster or finds a molecule classical searched missed, physicists at the company will call that a win, even if the drug still has years of life-cycle ahead.

Conclusion

IBM Quantum is positioning itself at the forefront of the quantum computing revolution in pharmaceuticals. Through a combination of cutting-edge hardware development, open-source software, and strategic collaborations (with Moderna, Algorithmiq, and research institutes), IBM is actively shaping how quantum algorithms will impact drug discovery and development. The case studies demonstrate real progress on hard problems like RNA folding and molecular simulation, validating IBM’s approach of hybrid quantum-classical workflows.

At the same time, we note that these efforts are largely experimental and research-oriented. We are witnessing the maturation of a field, not yet a fully deployed technology. However, the conviction behind IBM’s actions is clear: if quantum computing lives up to even a fraction of its promise, it will unlock previously impossible searches for better medicines, much faster and cheaper. Leading industry analysts (McKinsey, BCG) and investors (Novo Holdings, venture capital) echo this belief, projecting multibillion-dollar impacts. IBM’s own metrics – both their hardware milestones (e.g. Osprey at 433 qubits, soon Heron/Condor) and software developments (CVaR-VQE, Qiskit Nature functions, etc.) – suggest a credible path forward.

In conclusion, IBM Quantum’s initiatives in pharmaceuticals exemplify how a technology leader attempts to bridge from proof-of-concept to utility. By partnering directly with drug developers and embedding their tools in biological R&D, IBM is not merely speculating on future value, but incrementally working to generate near-term returns (research output, IP, skill-building) while laying the groundwork for long-term transformation. For stakeholders in both the quantum and pharma communities, IBM’s ongoing projects serve as bellwethers. If IBM’s quantum computers become powerful enough and the algorithms sophisticated enough to yield clear advantages in drug design, we will witness a genuine revolution in how therapies are discovered and optimized in the 21st century.
