Expanding partnership with Quantinuum to accelerate quantum-AI hybrid supercomputing

On November 10, a ceremony was held on RIKEN’s Wako campus to mark an expansion of the partnership between RIKEN and Quantinuum, a leading full-stack quantum computing company, with the goal of advancing quantum-AI hybrid supercomputing. Following a significant upgrade to Quantinuum’s Reimei quantum computer at RIKEN, the partners will pursue more advanced scientific and industrial applications, work with Japanese universities and suppliers toward the development of a “Made with Japan” fault-tolerant quantum computer, and collaborate with SoftBank Corp. to explore the connection of quantum computer with AI data centers in Japan. The partners will use the upgraded platform to combine quantum computing, supercomputing and AI in support of use case development across electronics, energy and life sciences.

“With the upgraded Reimei quantum computer, we will be able to tackle more complex and larger-scale scientific problems that were difficult to address with the previous H1 system, further advancing quantum–HPC hybrid computing through our ongoing JHPC-quantum project,” says Mitsuhisa Sato, Division Director of the Quantum-HPC Hybrid Platform Division at the RIKEN Center for Computational Science (R-CCS). “Furthermore, the newly signed Memorandum of Understanding will pave the way for expanding our research into the use of quantum computing for AI for Science, a key initiative being promoted by RIKEN.”
