Cambridge to host UK’s most powerful quantum computer in landmark IonQ partnership
The University of Cambridge is set to host the UK’s most powerful quantum computer as part of a major new partnership with US-based quantum technology firm IonQ, marking the University’s largest-ever corporate research collaboration.
The agreement will see the creation of the IonQ Quantum Innovation Centre at Cambridge’s Ray Dolby Centre, home to the Cavendish Laboratory. At its core will be a state-of-the-art 256-qubit quantum computer, expected to become the most powerful system of its kind in the UK once operational.
The facility is designed to accelerate research and commercial development across quantum computing, networking, sensing and security. It will also support new academic posts, postdoctoral researchers and PhD students, strengthening Cambridge’s already significant quantum research ecosystem.
Access to the system will extend beyond the University. Innovate UK will provide researchers and early-stage companies nationwide with computing time via the UK Research and Innovation National Quantum Computing Centre over a three-year period, enabling broader use of what is described as the UK’s first commercial-scale quantum computer hosted at a university.
Professor Mete Atatüre, Head of the Cavendish Laboratory, said the partnership would “supercharge” Cambridge’s role in the UK’s national quantum programme, highlighting its multidisciplinary approach spanning physics, engineering, medicine and policy.
Quantum computers harness the principles of quantum mechanics to perform calculations far beyond the reach of classical machines. The transition from experimental systems to application-focused platforms is expected to unlock advances in areas such as ultra-secure communications, advanced sensing and drug discovery.
The partnership also includes long-term research funding and plans to co-develop quantum network infrastructure, including strengthening the existing Cambridge-to-Bristol quantum network.
Professor Deborah Prentice, Vice-Chancellor of Cambridge, described the initiative as “the first of its kind for a UK university” and said it would help train the next generation of quantum scientists while delivering technologies with national impact.
IonQ CEO Niccolò de Masi said the agreement deepens the company’s commitment to the UK and strengthens links between academic research and commercial deployment of quantum technologies.
The collaboration aligns with the UK’s National Quantum Strategy and is expected to support economic growth, job creation and technological leadership. Science Minister Lord Vallance said the investment would help ensure the UK remains at the forefront of quantum innovation while addressing major societal challenges.
The quantum computer will be managed by Cambridge Enterprise, with access available to researchers across the University once fully operational.
