Hitachi to participate in Phase 2 research projects of JST Moonshot Research & Development Program Goal 6: “Realization of a fault-tolerant universal quantum computer that will revolutionize economy, industry, and security by 2050”
Tokyo, March 3, 2026 Hitachi, Ltd. (TSE: 6501, “Hitachi”) announces that it will participate in the Phase 2 (FY2026–FY2030) research and development projects under Moonshot Research & Development Program Goal 6, “Realization of a fault-tolerant universal quantum computer that will revolutionize economy, industry, and security by 2050” (Program Director: KITAGAWA Masahiro) led by the Japan Science and Technology Agency (JST). Specifically, Hitachi will participate in the projects: “Development of Fault-Tolerant Silicon Quantum Computer Technology” (Project Manager: TARUCHA Seigo) and “Neutral Atom-Based Fault-Tolerant Quantum Computer” (Project Manager: OHMORI Kenji).
In the former project, Hitachi will collaborate with RIKEN to realize a fault-tolerant silicon quantum computer*1. The partners aim to develop fault-tolerant qubit devices, targeting 100 qubits*2 by FY2028 and progressing toward a 1,000-qubit-scale device by FY2030. Within this project, Hitachi will be responsible for technology development related to device design, prototyping, verification, and system integration. In the latter project, Hitachi will develop system performance evaluation software for a neutral atom-based quantum computer*3 being developed by the Institute for Molecular Science. This work will contribute to system design and the formulation of operational policies for actual hardware systems. Furthermore, the results from the latter project will also be applied to the former project and accumulated as evaluation and operational expertise that can be utilized across different approaches.
*1 Silicon quantum computer: A type of quantum computer that uses semiconductor technology to integrate qubits on a silicon substrate.
*2 Qubit: The smallest unit of information used in a quantum computer.
*3 Neutral atom-based quantum computer: A type of quantum computer that performs quantum computation by arranging and controlling electrically neutral atoms using lasers.
