Japan's Institute for Molecular Science has successfully launched "Shunkai," the nation's first full-stack neutral-atom quantum computer, marking a significant milestone in hardware-software integration for this specific modality. The system currently operates with approximately 50 qubits and is designed to scale toward 500 qubits by leveraging laser-controlled neutral atoms that offer advantages such as room-temperature operation and flexible qubit configuration. This development aims to address critical challenges in scalability and error correction, potentially expanding to 10,000 physical qubits by 2031 for external research use.
Japan’s Full-Stack Neutral-Atom Quantum Computer is Operational

Insider Brief PRESS RELEASE — Institute for Molecular Science (IMS), National Institutes of Natural Sciences, announced on Aug. 24 that Japan’s first full-stack neutral-atom quantum computer “Shunkai,” developed by a research team led by Professor Kenji Ohmori, is now operational. Quantum computers are being developed in various modalities worldwide. However, there remain challenges to address […]
Japan's Institute for Molecular Science has begun operating Shunkai, the country's first full-stack neutral-atom quantum computer, integrating hardware and software in a system initially using about 50 qubits. Developed with Hitachi and Infleqtion under Japan's Moonshot R&D Program, Shunkai uses laser-controlled neutral atoms as qubits and is expected to scale to about 500 qubits while supporting external research and quantum error-correction development. The project aims to expand the platform to 10,000 physical qubits with quantum error detection and correction capabilities by March 2031,…
