Munich, Germany; Toulouse, France; and Cambridge, UK, August 2nd, 2023 — Airbus, BMW Group and Quantinuum, world leaders in mobility and quantum technologies, have developed a hybrid quantum-classical workflow to speed up future research using quantum computers to simulate quantum systems, focusing on the chemical reactions of catalysts in fuel cells.
In a new technical paper, "Applicability of Quantum Computing to Oxygen Reduction Reaction Simulations“, the three partners report accurately modeling the oxygen reduction reaction ("ORR") on the surface of a platinum-based catalyst. The ORR is the chemical reaction in the process that converts hydrogen and oxygen into water and electricity in a fuel cell and it limits the efficiency of the process. It is relatively slow and requires a large amount of platinum catalyst, so there is great interest and value in better understanding the underlying mechanisms involved in the reaction.
Using Quantinuum's H-Series quantum computer, the collaboration team has demonstrated the applicability of quantum computing in an industrial workflow to enhance our understanding of a critical chemical reaction. The three companies plan further collaboration to explore the use of quantum computing to address relevant industrial challenges.
Dr. Peter Lehnert, Vice-President, Research Technologies at BMW Group stated: “Circularity and sustainable mobility are putting us on a quest for new materials, to create more efficient products and shape the future premium user experience. Being able to simulate material properties to relevant chemical accuracy with the benefits from the accelerating quantum computing hardware is giving us just the right tools for more speed in innovation for this decisive domain.”
As a pioneer in the global automotive market BMW Group recognizes the transformative potential of quantum computing and its importance in researching new materials, where it can enable faster and more efficient processes while reducing lab prototypes. Approaching and accurately simulating one of the most fundamental electrochemical processes for the first time using quantum computing marks a substantial step towards the sustainable energy transition, benefiting metal-air batteries, and other products with enhanced efficiency.
Isabell Gradert, Vice-President, Central Research & Technology at Airbus said: “We can clearly envision the benefits of the study in our quest for sustainable and hydrogen powered alternatives such as the ZEROe aircraft, which may operate on fuel cell engines. The study confirms that quantum computing is maturing at the scale we need for aviation.”
Airbus has identified hydrogen as a promising candidate to power low-carbon aircraft, because it emits no CO2 when flying, when generated from renewable energy. The company previously announced plans to start testing a hydrogen-powered fuel cell propulsion system onboard its ZEROe demonstrator aircraft in the next few years. The company has the ambition to develop the world’s first hydrogen-powered commercial aircraft for market entry by 2035.
Ilyas Khan, Chief Product Officer, Quantinuum said: “We have been excited to be working for some time now to support the BMW Group and Airbus, both leaders in their fields, and both of whom recognize that quantum computing could play a pivotal role in advancing future sustainable mobility. In this pioneering work, we demonstrate how to integrate quantum computing into the industrial workflows of two of the world's most technologically advanced companies, tackling material science problems that are a prime target for progress using quantum computing."
The research team hopes that understanding the ORR reaction provides insights that help them identify alternative materials that may improve the performance and reduce the production costs of fuel cells. Modeling chemical reactions such as the ORR accurately is an intractable task for classical computers, due to the quantum properties of the chemical mechanisms involved, making such simulations a good candidate to benefit from a potential quantum advantage in the future.

Broomfield, Colorado, May 5th, 2026 — Quantinuum and BMW Group have formally expanded their ongoing collaboration into a multi-year partnership with a mission to unlock future mobility by applying quantum computing toward advanced materials science.
Since 2021, Quantinuum and BMW Group have been collaborating on joint research focused on tackling complex challenges in industrial chemistry to support the advancement of next-generation mobility. The collaboration has progressed from foundational algorithm development to advanced simulations of molecular systems, allowing the researchers to unlock insights into catalytic activity, reaction pathways, and material performance in energy-relevant environments.
The companies have now agreed to extend the work, positioning the alliance to become one of the longest-sustained commitments between a commercial enterprise and a quantum computing provider to date.
“Quantinuum is focused on driving commercial adoption of quantum computing through close collaboration with industry leaders on high-impact applications," said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “Our expanded partnership with the BMW Group underscores this focus, and we’re excited to scale the meaningful work we’ve been advancing together.”
Researchers at BMW Group are utilizing Quantinuum's trapped-ion architecture, which provides the high-fidelity operations necessary to accurately simulate molecular systems, particularly electrochemical processes that play a critical role across a range of technologies relevant to sustainable mobility and the design and optimization of fuel cells.
Under the terms of the agreement, BMW Group will leverage successive generations of Quantinuum’s quantum computers. This includes the current Helios system and upcoming generations, Sol (planned for 2027) and Apollo (planned for 2029). This will enable the teams to validate progress at each stage while scaling toward industrially meaningful solutions.
“We have been exploring quantum computing for many years,” said Dr. Martin Tietze, Vice President of New Technologies at BMW Group. “Together with partners such as Quantinuum, we translate advances in quantum hardware into real‑world applications, including materials optimization, supporting the development of future vehicle generations.”
Quantinuum’s progress toward large-scale, fault-tolerant systems helps to ensure that as the hardware reaches milestones in performance, BMW can apply that computational power to catalyst chemistry research, targeting critical oxygen reduction reaction processes at platinum catalysts to potentially lower costs and improve energy efficiency.
The companies broke new ground in 2024, alongside another commercial partner, as the first to simulate catalytic performance using a quantum computer with results published in Nature Partner Journal.
Beyond its technical achievements, the collaboration has evolved into a deeply connected, cross-disciplinary effort, bringing together quantum scientists, chemists, and engineers in a sustained partnership that reflects both the complexity of the challenge and the scale of the ambition.
