ULVAC Develops Dilution Refrigerator for Quantum Computers
– Supporting Japan’s First Fully Domestic Quantum Computer with Cryogenic Innovation
(2025/04/24)
ULVAC, Inc. and ULVAC CRYOGENICS INC. have successfully developed a dilution refrigerator designed for quantum computing applications. On April 4, 2025, the unit was installed at a leading quantum research institute in Japan. This achievement marks a critical milestone in the development of the country’s first fully Japan-built quantum computer―realized using only domestically developed core components.
Until now, Japan has faced the long-standing challenge of building a quantum computer entirely from domestically sourced technologies. ULVAC’s cryogenic solution, now operating as a core part of this quantum system, demonstrates Japan’s growing competitiveness in the global quantum race. Localized development enables flexible scalability, secure supply chains, and lower operational risks for users. Among these elements, the dilution refrigerator―ensuring a stable cryogenic environment essential for high-precision qubit operations―plays a vital role in enabling both deployment and long-term usability.
This quantum computer will be publicly demonstrated at the Expo 2025 Osaka, Kansai, Japan during the “entangle moment – [quantum | earth | universe] × art” event, to be held from August 14-20. Visitors will be able to interact with the system via the cloud, experiencing real-time quantum operations firsthand.
