Infleqtion has successfully deployed a 100-qubit quantum computing system at the UK National Quantum Computing Centre, marking a significant milestone in the country's quantum computing capabilities. The system, based on Infleqtion's Sqale neutral-atom architecture, became operational in December 2025 and is now a key component of the centre's Quantum Computing Testbed Initiative. This deployment provides the UK with its only operational 100-physical-qubit quantum computing system, positioning the country for advancements in quantum research and development. The Sqale platform's neutral-atom architecture is notable for its potential to scale up to thousands of qubits, making it an attractive option for large-scale quantum computing applications1. The successful deployment of this system is a crucial step forward for the UK's quantum computing ambitions, and its impact will be felt by researchers and practitioners seeking to leverage the power of quantum computing to drive innovation and solve complex problems.
