Quantinuum and RIKEN Expand Collaboration to Advance Commercialization of Japan's Quantum-AI Hybrid Supercomputers

On November 10, Quantinuum disclosed that it has expanded its partnership with Japan's Institute of Physical and Chemical Research (RIKEN), further advancing research and commercialization of quantum-AI hybrid supercomputing in Japan following the upgrade of the Reimei quantum computer deployed at RIKEN to the System Model H2.⁠

This upgrade establishes RIKEN’s hybrid quantum-supercomputing platform as the most capable system of its kind, paving new pathways for research in electronics, energy, and life sciences. The partners will collaborate with Japanese universities and domestic suppliers to develop fault-tolerant “Made with Japan” quantum computers, and work with SoftBank Corp. to explore infrastructure that directly connects quantum computers to AI data centers to support commercial applications.⁠

The collaboration is based on the NEDO-supported JHPC-quantum project, integrating Reimei, the ROQUO GPU supercomputer, and the Fugaku supercomputer. Related research has already covered areas such as material and biomolecular simulations, with preliminary results indicating that quantum data can enhance the predictive performance of AI models. Quantinuum CEO Rajeeb Hazra stated that following the upgrade, they will expand their collaborative exploration with RIKEN in these fields, and jointly advance industry accessibility with SoftBank.
