ԹϺ's System Model H1 Ion-trap Quantum Computer
Accelerates application development for quantum computers and supercomputers by project leaders RIKEN, SoftBank, University of Tokyo, and Osaka University
Broomfield, Colorado and London, UK, January 9th, 2024—ԹϺ, the world’s largest integrated quantum computing company, and RIKEN, Japan's largest comprehensive research institution and home to a world-leading high-performance computing (HPC) center, have announced an agreement in which ԹϺ will provide access to ԹϺ’s highest H1-Series ion-trap quantum computing technology to RIKEN. Under the agreement, ԹϺ will install the hardware at RIKEN’s campus in Wako, Saitama.
The deployment will be part of RIKEN’s project to build a quantum-HPC hybrid platform consisting of high-performance computing systems, such as the supercomputer Fugaku and quantum computers. The integrated hardware platform will support a large-scale software research program in which researchers at RIKEN – together with collaborators Softbank, University of Tokyo, and Osaka University - will develop the software tools and applications required to integrate quantum computers and supercomputers most effectively.
As the project goal, RIKEN and its collaborators aim to demonstrate the advantages of such hybrid computational platforms for deployment as services in the future post-5G era. This project is commissioned by the New Energy and Industrial Technology Development Organization (NEDO), a national research and development agency under Japan’s Ministry of Economy, Trade and Industry.
“We are honored to be selected to be part of this ambitious, advanced project in Japan,” said Dr. Rajeeb Hazra, CEO of ԹϺ. “ԹϺ has a track record as a commercial leader in quantum computing, and we hope to bring our technical and operational know-how and contribute to achieving the project’s objectives. Our H-Series quantum computer is uniquely poised to enable ground-breaking developments by researchers around the world1. We are excited that this engagement will allow researchers in RIKEN and other Japanese institutions to benefit from our H-Series quantum computer’s full power and capability.”
“Advanced quantum computers of NISQ are now moving into the practical stage as the number of qubits is increasing and the fidelity is improved. From the HPC’s point of view, quantum computers are devices that accelerate scientific applications conventionally executed on supercomputers and enable computations that cannot yet be solved by supercomputers. RIKEN is committed to developing system software for quantum-HPC hybrid computing, by leveraging its comprehensive scientific research capabilities and experience in the development and operation of cutting-edge supercomputers, such as Fugaku,” said Dr. Mitsuhisa Sato, Deputy Director, RIKEN Center for Computational Science / Director, Quantum HPC Collaborative Platform Division.

RIKEN Scales Quantum-Supercomputing in Japan with ԹϺ System Upgrade
TOKYO — April 14, 2026 — ԹϺ, 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 ԹϺ’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, ԹϺ 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 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 ԹϺ, said: “We believe RIKEN’s decision to continue adopting ԹϺ systems to meet its ambitious objectives is a validation of our technology roadmap and a reflection of the success of our valued partnership. With ԹϺ 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 ԹϺ and RIKEN’s collaboration to advance quantum-HPC hybrid infrastructure in Japan. ԹϺ 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.
