On March 27, 2023, a consortium led by RIKEN made Japan’s first domestically produced superconducting quantum computer available through a cloud service. The 64-qubit machine was developed under the Q-LEAP program by RIKEN, the National Institute of Advanced Industrial Science and Technology (AIST), the National Institute of Information and Communications Technology (NICT), Osaka University, Fujitsu, and NTT.
According to a joint announcement by the research partners, the cloud service was initially available for non-commercial use to researchers and engineers in Japan under joint research agreements with RIKEN. The quantum computer used two-dimensional integrated circuits and perpendicular wiring packages designed at the RIKEN Center for Quantum Computing.
RIKEN and Fujitsu planned to provide a superconducting quantum computer for industrial use by the end of FY2023. The domestic machine complemented an IBM Quantum System One already installed at the University of Tokyo in 2021.
