Milestone Achievement at the National Quantum Computing Centre
On March 16, 2026, Infleqtion (NYSE: INFQ), a leader in quantum technology, announced the delivery of the United Kingdom's only operational 100-physical-qubit quantum computing system at the National Quantum Computing Centre (NQCC) in Oxford. This achievement, realized in December 2025, is a pivotal milestone in the UK's quantum strategy, aimed at transitioning from research to practical applications in quantum computing.
The deployment of the Sqale platform at the NQCC is part of a broader initiative to establish a Quantum Computing Testbed, which will facilitate research and application development on large-scale quantum systems. Lord Vallance, Minister of State for Science, Research and Innovation, emphasized the significance of this advancement, stating that it helps position the UK as a leader in quantum technology and enables tangible benefits from quantum computing.
Implications for Research and Industry
The introduction of the 100-qubit system allows researchers to move beyond small-scale demonstrations and engage in more complex quantum experiments. Dr. Michael Cuthbert, Director of the NQCC, noted that this system will enable the quantum community to learn how to operate and scale quantum computers effectively. The NQCC's initiative aims to foster skills development and supply-chain readiness across the UK quantum ecosystem.
Colin Sullivan, Managing Director of Infleqtion UK, remarked on the importance of this milestone for the UK’s ambition to build world-class sovereign quantum capabilities. Infleqtion's roadmap includes plans to exceed 30 logical qubits in 2026 and more than 100 logical qubits by 2028, with a focus on achieving fully fault-tolerant architectures.
Technical Advancements and Future Prospects
Infleqtion's neutral-atom architecture is recognized for its scalability, reconfigurability, and strong coherence properties, making it a promising approach for developing larger quantum systems. The company has achieved a two-qubit gate fidelity of 99.73%, which is critical for the performance of quantum computers. This high fidelity allows for fewer physical qubits to encode a reliable logical qubit, enhancing scalability and efficiency.
The operational Sqale platform will support various applications, including advanced materials, energy systems, and complex optimization problems. This deployment marks a significant step toward practical quantum computing solutions that can address real-world challenges.
Official Statements & Responses
Infleqtion's leadership expressed pride in this achievement, highlighting its role in advancing the UK's quantum technology landscape. Matthew Kinsella, CEO of Infleqtion, stated, “This latest achievement with Sqale reflects the progress and potential of our neutral-atom architecture.” The NQCC's initiative is seen as a critical component of the UK's national quantum infrastructure, enabling researchers to benchmark applications and explore practical research opportunities.
What's Next for Quantum Computing in the UK
With the Sqale platform now operational, researchers and industry collaborators are poised to evaluate large-scale quantum computing capabilities in a national testbed environment. This development supports ongoing efforts to advance quantum technology and solidifies the UK's position in the global quantum landscape. The collaboration between Infleqtion and the NQCC is expected to unlock further potential in quantum applications, paving the way for innovations that could transform various sectors.
