Infleqtion Delivers the UK's Only Operational 100-Qubit Quantum Computing System at the National Quantum Computing Centre

Infleqtion has delivered the UK's only operational 100-physical-qubit quantum computing system at the National Quantum Computing Centre using its Sqale platform. The milestone was achieved in December 2025 and was identified Lord Vallance, Minister of State for Science, Research and Innovation, said the progress is a significant milestone helping move the UK beyond research toward real-world uses. Such advances are vital for using quantum computers to deliver tangible benefits and help cement the UK's position as a world leader in the technology, he said. Matthew Kinsella, CEO of Infleqtion, said the achievement with Sqale reflects the progress of the neutral-atom architecture and marks an important step toward larger-scale systems. The company is proud to partner with the NQCC on a platform critical to advancing quantum computing, Kinsella said. The deployment is part of the NQCC's Quantum Computing Testbed Initiative. Researchers can evaluate performance, benchmark applications and study scaling of neutral-atom systems. The platform accelerates skills development, supply-chain readiness and application exploration across the UK quantum ecosystem. Dr Michael Cuthbert, Director of the NQCC, said having a system of this scale available is a significant step for the UK quantum community. It allows researchers to move beyond small demonstrations and begin learning what it really takes to operate and scale quantum computers in practice, he said. Colin Sullivan, Managing Director of Infleqtion UK, said this is a defining moment for Infleqtion and the UK's ambition to build world-class sovereign quantum capabilities. Achieving this milestone has been a key goal and the team is immensely proud of seeing it become reality, he said. Infleqtion looks forward to expanding its partnership with UK researchers, businesses and government to unlock the full potential of quantum technology, Sullivan added.
