Infleqtion Supplies QPU for Japan’s ‘Shunkai’ Neutral-Atom Quantum Computer

LOUISVILLE, Colo., Aug. 24, 2026 — Infleqtion, a global leader in quantum computing and quantum sensing powered by neutral-atom technology, has helped Japan reach a major quantum milestone, supporting a research team led by Professor Kenji Ohmori at the Institute for Molecular Science (IMS), part of the National Institutes of Natural Sciences, in launching the country’s first operational neutral-atom full-stack quantum computer. Infleqtion was also the only foreign quantum partner selected by the Japan Science and Technology Agency (JST) for its Quantum Moonshot program.

Infleqtion contributed its quantum processing unit to the program, in collaboration with the Ohmori group at IMS, as one of the principal investigators of the Moonshot project led by Professor Ohmori, supporting the transition from research and development to an operational full-stack quantum computing platform. The system, referred to as “Shunkai”, is initially expected to operate with approximately 50 qubits, with plans to scale to around 500 qubits as development progresses.

“This milestone marks a pivotal moment for Japan’s quantum ambitions as well as Infleqtion’s role in advancing production-ready quantum platforms at scale,” said Pranav Gokhale, Chief Technology Officer at Infleqtion. “Bringing a full-stack quantum system into production operation is a meaningful step toward fault-tolerant quantum computing that also serves as strong validation of neutral-atom architecture. Our quantum processing unit delivers the programmability, scalability and fidelity control that next-generation systems demand.”
