The project, spearheaded by QIQB, along with RIKEN and leading Japanese companies achieved complete technological self-reliance by replacing previously imported components, such as the dilution refrigerator and pulse tube refrigerator with domestic alternatives. Furthermore, the entire software ecosystem, from front-end to back-end, is open-source and developed in Japan, leveraging the Open Quantum Toolchain for OPerators & USers (OQTOPUS).
This project demonstrates Japan’s comprehensive mastery of the different technologies required for quantum computer manufacturing and system integration. Quantum computers hold immense potential for addressing global challenges, from developing new materials and medicines to optimizing complex systems and mitigating environmental impact. They also promise to revolutionize everyday life through advancements in fields like machine learning.
From Aug. 14-20, Expo 2025, Osaka, Kansai, Japan will host a special exhibition titled “entangle moment – [quantum, ocean, universe] x art,” showcasing components of the domestically produced quantum computer. Visitors will have the unique opportunity to connect to the system remotely via cloud access and perform simple quantum programs, gaining firsthand experience with this cutting-edge technology.
The exhibit, designed to be accessible to a wide audience regardless of technical expertise, also features interactive elements exploring quantum entanglement and other quantum phenomena. In collaboration with Professor Akihiro Kubota of Tama Art University, the exhibit will include quantum computer-generated art, further bridging the gap between science and artistic expression. This Expo exhibit promises to provide an engaging and informative experience, demystifying quantum technology and inspiring the next generation of quantum innovators.
