Neutral-atom quantum computing project

Greeting

A neutral-atom quantum computer utilizes the arrays of atoms — assembled with optical tweezers — whose temperature is almost absolute zero. Each single atom in this array serves as a high-quality qubit, whereas the whole system operates at room temperatures. It has rapidly been attracting the attention of industry, academia, and government worldwide for the past four or five years as a quantum computing hardware technology representing the next generation. Launched in November 2022 and entering its second phase (Japanese fiscal years 2026 - 2030) this April, the Ohmori Moonshot Project develops, operates, and upgrades a neutral-atom fault-tolerant quantum computer system. In particular, we fully leverage the various core competencies of the Ohmori Project, including qubit manipulation, scaling, ultrafast laser technology, and systems engineering. Through close industry-academia collaboration, we modularize and package all components, achieving unprecedented levels of stability and usability. Furthermore, through close collaboration with Yaqumo Inc. — a spin-out startup from the Ohmori Moonshot Project — we aim to achieve the societal implementation of practical quantum computers. We look forward to your continued support.
