Breakthrough: 100-Qubit Quantum Computer Unveiled in UK

Infleqtion Deploys 100-Qubit Quantum System at UK's National Centre

Infleqtion has reached a major milestone in quantum computing by deploying a 100-physical-qubit neutral-atom system at the UK’s National Quantum Computing Centre (NQCC). The achievement, announced in December 2025, marks a step forward for practical quantum applications beyond research labs. Industry leaders and government officials have hailed the development as a turning point for the UK’s quantum ambitions. The newly installed system, called Sqale, is the first neutral-atom platform of its size to operate within a national facility. Unlike many competitors still focused on theoretical work, Infleqtion’s technology is designed for real-world use. Tests confirmed a 99.73% two-qubit gate fidelity, a key factor in building reliable logical qubits and scaling up performance.

Infleqtion has set ambitious targets based on this progress. The company plans to surpass 30 logical qubits by 2026 and deliver over 100 by 2028. These advances could accelerate solutions in fields like materials science and energy, where complex calculations are needed. Colin Sullivan, Managing Director of Infleqtion UK, called this a defining moment for both the company and the UK’s push for sovereign quantum capabilities. Matthew Kinsella, Infleqtion’s CEO, added that the NQCC’s testbed is among the first globally to drive innovation at this scale. Lord Vallance, Minister of State for Science, Research and Innovation, also praised the breakthrough as a significant step for the nation’s quantum strategy.

The installation at the NQCC shifts the UK from research-focused quantum experiments toward practical, large-scale applications. With high-fidelity qubits and a clear roadmap for expansion, Infleqtion’s system positions the country as a leader in neutral-atom quantum technology. The next phases will focus on scaling logical qubits and addressing real-world challenges in science and industry.
