TL;DR
Quantinuum and RIKEN say their Reimei quantum computer at RIKEN has been upgraded to Quantinuum’s System Model H2, expanding the platform used for quantum-HPC research. The partners also plan work with Japanese universities and suppliers toward a fault-tolerant quantum computer, while Quantinuum, RIKEN and SoftBank will explore links between quantum computers and AI data centers. Research results described by the partners are preliminary, and the commercial and fault-tolerant plans remain under development.
Quantinuum and RIKEN have expanded their quantum-computing partnership in Japan after upgrading the Reimei quantum computer at RIKEN to Quantinuum’s System Model H2. The partners say the system will support more complex research combining quantum computing, supercomputing and AI, as they also work toward a fault-tolerant computer developed with Japanese universities and suppliers and explore industry access through AI data centers with SoftBank.

Reimei operates at RIKEN as part of the JHPC-quantum project, which is funded by Japan’s New Energy and Industrial Technology Development Organization, or NEDO. Quantinuum and RIKEN say the upgrade expands the capabilities of the project’s quantum–high-performance computing platform. They expect it to let researchers study larger or more complex quantum systems that are difficult to simulate using classical computing alone; the announcement does not provide benchmark figures quantifying the improvement.
The partners plan to use the upgraded platform for applications in electronics, energy and life sciences. They describe two research efforts already operating on Reimei ahead of a public launch of its services. In one, researchers use quantum-generated data from Reimei to train an AI model for magnetism simulations on RIKEN’s JHPC-quantum GPU supercomputer, ROQUO. The partners report preliminary results in which the model predicts more accurately than AI models trained only on classical simulations, and more precisely than the quantum computer itself. Those findings are preliminary, not a reported commercial outcome.
A second effort combines Reimei, RIKEN’s Fugaku supercomputer and an NVIDIA evolutionary AI agent running on ROQUO to simulate a photoactive biomolecule. The researchers are seeking greater scale and detail in modeling how biomolecules respond to light. The partners say that work could inform future applications, including solar cells, but have not reported a finished product or demonstrated industrial benefit.
From Research Platform to Industry
The upgraded system gives researchers a new platform for testing how quantum processors, supercomputers and AI can be used together on scientific problems. The significance for now is research capacity: the partners say the upgrade allows them to investigate more complex systems, while their early projects offer examples of how quantum-generated data might contribute to AI models and simulations. The announcement does not establish that these methods outperform existing approaches across a wider range of tasks.
The industrial plans extend the partnership beyond laboratory research. Quantinuum and RIKEN intend to draw on their experience operating Reimei as they work with Japanese universities and component suppliers toward a fault-tolerant quantum computer. Separately, the three partners plan to examine whether quantum computers could connect with AI data centers in Japan, and whether that infrastructure could support services for businesses. These are development and feasibility efforts, not commitments to a delivery date or a finished commercial service.

Reimei and the JHPC-Quantum Project
The announcement builds on a years-long collaboration between Quantinuum and RIKEN, Japan’s national research institute. Reimei is installed at RIKEN and is operated through JHPC-quantum, a project linking quantum computing with high-performance computing. The upgrade changes the system from the earlier H1 model to Quantinuum’s System Model H2, according to the announcement.
RIKEN says the broader research also supports its AI for Science initiative. The announcement places the work alongside U.S.-Japan efforts to advance AI-driven discovery and mentions a planned $1 billion partnership under the U.S. Genesis Mission. It does not give further terms or details of that planned partnership, and it does not say that the Quantinuum-RIKEN work is funded by it.
Alongside the upgrade, Quantinuum, RIKEN and SoftBank signed a separate agreement to explore connecting quantum computers to AI data centers in Japan. The partners say they will assess infrastructure readiness and consider how connected systems might provide hybrid computing services. This is distinct from the research work underway on Reimei and remains at the exploration stage.
“Japan’s quantum ambitions require advanced capabilities today and a sustained commitment to developing what comes next.”
— Dr. Rajeeb Hazra, Quantinuum CEO
Results and Delivery Dates
The announcement does not state when Reimei’s services will be publicly available, provide technical performance benchmarks for the H2 upgrade, or specify how many researchers or businesses will gain access. The magnetism-model results are described as preliminary; the partners do not provide figures, independent validation or details sufficient to judge how broadly they apply.
No completion date, technical specification, budget or development schedule is given for the proposed fault-tolerant “Made with Japan” computer. The partners also have not announced a decision to build a particular connection between quantum systems and AI data centers, or a launch date, pricing or service model for commercial access. These points remain subject to further research and infrastructure assessment.
Research and Infrastructure Assessment
Quantinuum and RIKEN say they will use the upgraded Reimei platform to pursue research in electronics, energy and life sciences, while working with Japanese universities and domestic suppliers on the fault-tolerant-computing effort. The next public milestones will be further project details or research results; the announcement provides no timetable for either.
Under their separate agreement, Quantinuum, RIKEN and SoftBank will explore infrastructure requirements for connecting quantum computers with AI data centers in Japan. Whether that work leads to a deployed service will depend on the assessment and decisions that follow. The partners have not announced a date for those findings or a commercial launch.
Key Questions
What changed in the Quantinuum-RIKEN partnership?
The partners announced an expanded collaboration after upgrading the Reimei quantum computer at RIKEN to Quantinuum’s System Model H2. Their plans cover research, longer-term fault-tolerant system development and exploration of links to AI data centers.
