R&D Project
Goal 6 R&D Projects (Selected in FY2025)Neutral Atom-Based Fault-Tolerant Quantum Computer
Project manager (PM)OHMORI KenjiProfessor/Chairman, Institute for Molecular Science, National Institutes of Natural Sciences
Summary of the project
Neutral-atom quantum computers use the arrays of ultracold atoms assembled with optical tweezers, in which each single atom serves as a high-quality qubit, whereas the whole system operates at room temperatures. We develop, operate, and upgrade neutral atom-based fault-tolerant quantum-computer systems, where we will fully utilize our various core competencies in qubit control / manipulation, scalability, ultrafast laser technologies, and system engineering (as exemplified in Fig. 1), etc. Tight industry-academia collaborations will lead to all the components modularized and packaged, achieving unprecedented levels of stability and usability.

Milestone by year 2030
A universal gate set with logical qubits is implemented. External users outside the Ohmori project run logical circuits with our quantum computer systems.
Milestone by year 2028
The effectiveness of quantum error correction is demonstrated. External users within the Ohmori project run quantum circuits with our quantum computer systems.
