About

The advanced convergence computational technology being addressed in G-QuAT is an R&D field highly attracting attention around the world. Related technologies are spread broadly, and international competition is intensifying. To perform R&D toward pioneering business development, agile research activities are necessary beyond the existing research fields. For this reason, G-QuAT was established directly under the leadership of the chief technical officer who manages all research areas addressed in AIST and is composed of nine research teams, a planning office and a collaboration promotion office.

Greeting from the Director

G-QuAT’s mission is to advance research in quantum technology, create new global markets utilizing this technology, and generate economic value through industry collaboration. By integrating quantum technology with existing technologies, G-QuAT aims to spread Japan-originated technologies and business models worldwide, enhancing competitiveness and building a robust business ecosystem. This includes providing start-up support and investment opportunities by leveraging AIST’s R&D capabilities and extensive network.

Established on July 27, 2023, with support from the Ministry of Economy, Trade and Industry (METI) and based on the government’s Quantum Strategy*, G-QuAT is equipped with state-of-the-art facilities and an optimal environment. It is expected to be a unique research center primarily offering industrial support to companies, and it is highly anticipated by government, industry, and other sectors both in Japan and internationally.

I have dedicated my career to research, development, and education, primarily in the field of semiconductors, and am deeply concerned about the decline in Japan’s research and development capabilities and its ability to foster new industries. G-QuAT is a significant organization operated by the government and METI with substantial funding. We are committed to working together to make G-QuAT a world-leading center for enhancing Japan’s industrial competitiveness, research capabilities, and human resource development.
