Introducing Quantinuum: The World's Largest Integrated Quantum Computing Company

• The companies plan to continue their co-creation partnership to advance future mobility
• BMW to access the latest generations of Quantinuum systems throughout the partnership
• Advanced materials science research supports a range of next-generation technologies

Broomfield, Colorado, May 5^th, 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.

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.

Tokyo, Japan, April 14^th, 2026 — Quantinuum, a leading quantum computing company, today announced that RIKEN, Japan’s premier national research institute, has procured its System Model H2 quantum computer to scale the capability of “Reimei-Fugaku,” a hybrid quantum-supercomputer platform in Japan.

The Reimei-Fugaku platform represents the frontier of computing technology. Launched in the spring of 2025, it combines Quantinuum’s "Reimei" quantum system with RIKEN’s "Fugaku," one of the world’s fastest supercomputers—more formally known as a high-performance computing (HPC) system.

Now, the hybrid compute platform is getting a substantial upgrade. Earlier this month, Quantinuum delivered its H2 system to RIKEN’s research facility near Tokyo, where assembly is already underway to replace its predecessor, System Model H1, which Reimei has been based on to date. The newer-generation, 56-qubit system is engineered for high-fidelity operations that can reduce time-to-solution, enable larger workloads, and support higher-value applications.

Technology leaders see hybrid compute systems as a practical way to overcome the limits of classical HPC. By combining the significant data-processing power of HPC with a quantum computer’s ability to model complex molecules and materials, researchers could be enabled to solve specialized mathematical problems that are impractical for classical systems to handle alone.  

Researchers have already demonstrated this potential using the current Reimei-Fugaku platform. In a workflow with relevance potentially extending to future pharmaceutical applications, they successfully simulated biomolecular reactions at an accuracy that would be infeasible for HPC to achieve in isolation.

With multiple studies in chemistry and materials science already underway on the platform, this H2 upgrade is expected to accelerate research and unlock even more complex scientific discoveries across disciplines.‍

Dr. Mitsuhisa Sato, Division Director of the Quantum-HPC Hybrid Platform Division, RIKEN Center for Computational Science, said: “Since its installation in February 2025, Reimei H1 has been widely used by JHPC-quantum users and has delivered significant results, thanks to its high fidelity and flexible qubit connectivity. The upgrade to H2 is exactly what we have been eagerly anticipating, and with its 56 qubits, we expect it to play a key role in demonstrating quantum advantage through quantum–HPC hybrid computing.”‍

Dr. Rajeeb Hazra, President and CEO of Quantinuum, said: “We believe RIKEN’s decision to continue adopting Quantinuum systems to meet its ambitious objectives is a validation of our technology roadmap and a reflection of the success of our valued partnership. With Quantinuum and RIKEN’s combined leadership in quantum and HPC, respectively, we expect to continue pushing the boundaries of computing to address some of the most critical and complex challenges facing science and industry today.”

This development reflects the continued progress of Quantinuum and RIKEN’s collaboration to advance quantum-HPC hybrid infrastructure in Japan. Quantinuum intends to continue working with the country’s research community to accelerate real-world use cases and contribute to the growth of its quantum ecosystem.
