Expert Statements
Rajeeb Hazra, CEO of Quantinuum
“Japan's quantum ambitions require advanced capabilities today and a sustained commitment to developing what comes next”
Rajeeb Hazra, CEO of Quantinuum
“The upgrade to Reimei expands what we can explore with RIKEN across electronics, energy and life sciences. Together, we are building on this work to develop a fault-tolerant quantum computer with Japanese universities and suppliers, while exploring with SoftBank how these capabilities can become accessible to industry through Japan's AI data centers.”
Mitsuhisa Sato, Division Director, Quantum-HPC Hybrid Platform Division, RIKEN Center for Computational Science (R-CCS)
“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”
Mitsuhisa Sato, Division Director, Quantum-HPC Hybrid Platform Division, 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.”
Takenori Kobayashi, Vice President, Head of Product Research & Development Division at SoftBank Corp.
“Japan has established a strong foundation for hybrid quantum-HPC computing through the NEDO-supported JHPC-quantum project”
Takenori Kobayashi, Vice President, Head of Product Research & Development Division at SoftBank Corp.
“Our responsibility is to turn these achievements into industrial value. Together with RIKEN and Quantinuum, we aim to advance a Quantum AI Datacenter that connects quantum computing with AI and HPC, making these capabilities accessible to businesses across Japan.”
