Quantum computer sources majority of components from Japanese makers

 

Tokyo and Osaka, December 20, 2023 – A consortium of joint research partners including
the Center for Quantum Information and Quantum Biology at Osaka University, RIKEN, the
Advanced Semiconductor Research Center at the National Institute of Advanced Industrial
Science and Technology (AIST), the Superconducting ICT Laboratory at the National Institute
of Information and Communications Technology (NICT), Amazon Web Services, e
trees.Japan, Inc., Fujitsu Limited, NTT Corporation (NTT), QuEL, Inc., QunaSys Inc., and
Systems Engineering Consultants Co.,LTD. (SEC) today announced the successful
development of Japan’s third superconducting quantum computer (1) installed at Osaka
University. Starting December 22, 2023, the partners will provide users in Japan access to
the newly developed computer via the cloud, enabling researchers to execute quantum
algorithms (2), improve and verify the operation of software, and explore use cases remotely.

The newly developed superconducting quantum computer uses a 64 qubit chip provided by
RIKEN, which leverages the same design as the chip in RIKEN’s first superconducting
quantum computer, which was unveiled to users in Japan as a cloud service for non
commercial use on March 27, 2023 (3).

For the new quantum computer, the research team sourced more domestically
manufactured components (excluding the refrigerator). The research team confirmed that
the new quantum computer, including its components, provides sufficient performance and
will utilize the computer as a test bed for components made in Japan.
