According to TechFlow, on November 10, Quantinuum disclosed that it had expanded its collaboration with Japan’s RIKEN (Institute of Physical and Chemical Research). Following the upgrade of the Reimei quantum computer deployed at RIKEN to System Model H2, the two organizations will further advance research and commercialization of Japan’s quantum-AI hybrid supercomputer.

The upgrade makes RIKEN’s hybrid quantum-supercomputing platform the most capable system of its kind, opening new avenues for research in fields such as electronics, energy, and life sciences. The two organizations will work with Japanese universities and domestic suppliers to develop a fault-tolerant quantum computer “Made with Japan.” In partnership with SoftBank Corp., they will also explore infrastructure for connecting quantum computers directly to AI data centers to support commercial applications.

The collaboration is based on the NEDO-supported JHPC-quantum project and combines the Reimei and ROQUO GPU supercomputers with the Fugaku supercomputer. Related research has covered areas such as materials and biomolecular simulations, with preliminary results showing that quantum data can improve AI model predictions. Quantinuum CEO Rajeeb Hazra said the upgrade would expand exploration with RIKEN in related fields and advance industry accessibility together with SoftBank.
