Quantinuum and RIKEN Expand Partnership to Accelerate the Commercialization of Quantum-AI Hybrid Supercomputing in Japan

Quantinuum upgraded its Reimei quantum computer to the H2 system at RIKEN, establishing the facility as the world's most capable hybrid quantum-supercomputing platform.
The partners will collaborate with Japanese universities and domestic suppliers to develop a fault-tolerant "Made with Japan" quantum computer.
A separate agreement with SoftBank Corp. aims to connect quantum computers directly with AI data centers to accelerate commercial adoption.
The upgraded H2 system enables research in electronics, energy, and life sciences using a hybrid architecture combining quantum computing, supercomputing, and AI.
Two initial research projects utilize the platform: Quantum-AI for materials simulation to improve magnetism predictions for technologies like MRI, and Quantum-AI for biomolecular simulation to enhance solar cell design.
Dr. Mitsuhisa Sato of RIKEN stated the upgrade allows tackling complex scientific problems previously difficult to address with the H1 system.
The initiative aligns with RIKEN's AI for Science strategy and supports U.S.-Japan efforts including a planned $1 billion partnership under the U.S. Genesis Mission.
Funding for the JHPC-quantum project is provided by the New Energy and Industrial Technology Development Organization (NEDO).
