University of Osaka The machine operating in Osaka uses superconducting chipsUniversity of Osaka
Japan’s first superconducting quantum computer designed and built entirely with components developed domestically began operating at the University of Osaka at the end of July. The new system uses a chip with superconducting quantum bits, derived from metals that exhibit negligible electrical resistance when cooled to temperatures near absolute zero. All the components, including the quantum processing unit developed at the Institute for Research in Physics and Chemistry (RIKEN), are housed in a cryogenic device that allows for extremely low temperatures. Developed in partnership with companies such as Fujitsu, the new system runs on open-source software developed in Japan. Visitors to Expo 2025, held in Osaka in August, were able to connect to the system remotely and run basic quantum programs. Quantum computing still faces many barriers, including the limited number of algorithms with proven quantum advantage (University of Osaka, August 26).
