University of Osaka Debuts Fully Domestic Quantum Computer

The University of Osaka has announced the launch of Japan’s first superconducting quantum computer, designed and built entirely with domestic components and software. The system, which went live on 28 July at the university’s Center for Quantum Information and Quantum Biology (QIQB), represents a milestone in Japan’s ability to achieve complete technological self-reliance in quantum computing system design, manufacturing, and integration.

QIQB led the project in collaboration with RIKEN and Japanese companies including ULVAC, Inc., ULVAC CRYOGENICS INC., e-trees.Japan, Inc., QuEL, Inc., QunaSys Inc., Systems Engineering Consultants Co., LTD., TIS Inc., and Fujitsu Limited. Imported components such as the dilution refrigerator and pulse tube refrigerator were replaced with domestically manufactured equivalents. The entire software stack, from front-end to back-end, was developed in Japan as open-source, using the Open Quantum Toolchain for OPerators & USers (OQTOPUS).

From August 14-20, 2025, the University of Osaka will present a public exhibition, entangle moment – [quantum, ocean, universe] x art, showcasing components of the domestically produced quantum computer. Attendees will be able to connect to the system remotely via cloud access to run basic quantum programs. The exhibit, designed for accessibility to both technical and non-technical audiences, will feature interactive displays on quantum entanglement and other phenomena. In collaboration with Professor Akihiro Kubota of Tama Art University, the exhibition will also present quantum computer-generated art, blending scientific innovation with artistic interpretation.

The successful development of a fully domestic quantum system demonstrates Japan’s mastery of the hardware, software, and integration technologies required for advanced computing. Potential applications include accelerating materials and drug discovery, optimizing large-scale systems, mitigating environmental impacts, and enabling new capabilities in artificial intelligence and machine learning.
