Researchers at The University of Osaka’s Center for Quantum Information and Quantum Biology (QIQB), in collaboration with RIKEN and companies including ULVAC, Inc. and Fujitsu Limited, have successfully launched a fully domestically produced superconducting quantum computer on 28 July 2025. This achievement demonstrates Japan’s capacity to independently design, manufacture, and integrate a complete quantum system, replacing previously imported components with domestically developed alternatives and utilising the open-source Open Quantum Toolchain for OPerators & USers (OQTOPUS) software ecosystem.
Visitors to Expo 2025 Osaka, Kansai, Japan, from 14 to 20 August, will be able to interact with the system remotely via cloud access and experience simple quantum programs, alongside exhibits exploring quantum entanglement and computer-generated art in collaboration with Professor Akihiro Kubota of Tama Art University. The project received funding from the Ministry of Education, Culture, Sports, Science and Technology, the Japan Science and Technology Agency, and the Cabinet Office.
Japan has successfully launched its first completely homegrown superconducting quantum computer on July 28, 2025, at the University of Osaka’s Center for Quantum Information and Quantum Biology (QIQB). This achievement marks a significant technological milestone, demonstrating Japan’s complete self-reliance in quantum computing technology.
The project represents a collaborative effort between QIQB, RIKEN, and multiple Japanese companies including ULVAC, e-trees.Japan, QuEL, QunaSys, TIS, and Fujitsu. The team replaced all previously imported components with domestic alternatives, including critical cooling systems like dilution and pulse tube refrigerators. The entire software ecosystem runs on the open-source Open Quantum Toolchain for OPerators & USers (OQTOPUS), also developed in Japan.
This development positions Japan as a key player in the global quantum computing race, with the technology holding promise for breakthroughs in drug development, materials science, environmental solutions, and machine learning applications. The achievement demonstrates Japan’s comprehensive mastery of the complex technologies required for quantum computer manufacturing and system integration.
