Infleqtion’s Shunkai neutral atom Quantum Computer now operational

Infleqtion, a global provider of neutral-atom solutions for quantum computing, networking, sensing, and security, has launched Japan’s first operational neutral-atom full-stack quantum computer. 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.

The project supports a research team led by Professor Kenji Ohmori at the Institute for Molecular Science (IMS), part of the National Institutes of Natural Sciences. Infleqtion was selected by the Japan Science and Technology Agency (JST) for its Quantum Moonshot program that aims to enable the transition from research and development to an operational full-stack quantum computing platform.

“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.”
