The UK’s most powerful quantum computer, which will accelerate research and discovery in quantum science, engineering, and a range of other applications, will be based at the University of Cambridge as part of a new partnership with the quantum technology company IonQ. The collaboration is the University’s largest-ever corporate research partnership. The partnership will support the creation of the IonQ Quantum Innovation Centre to be based at the Ray Dolby Centre, the new home of Cambridge’s Cavendish Laboratory. The Centre will house a state-of-the-art IonQ 256-qubit quantum computer, which will be the most powerful quantum computer in the UK when it is installed. As part of the collaboration, Innovate UK, the UK’s innovation agency and part of UK Research and Innovation (UKRI), will provide access and computing time for UKRI’s National Quantum Computing Centre over three years. This support will enable researchers and early-stage companies from across the UK to make use of the enormous power of the first commercial-scale quantum computer at a UK university. The new IonQ Quantum Innovation Centre will host a research portfolio across quantum computing, quantum networks, quantum sensing, and quantum security. The partnership will also support new academic positions, postdoctoral fellows and PhD students at the University. “Cambridge is already a critical player in the UK’s national quantum technology programme, and this partnership will supercharge that role,” said Professor Mete Atatüre, Head of the Cavendish Laboratory. “This is a true partnership, with long-term investment, shared research and co-development in all areas of quantum technology, bringing together physics, engineering, medicine, computer science, policy and more.” Quantum computers harness quantum phenomena to achieve a level of performance which is otherwise unattainable, based on science which cannot be explained by classical physics. The shift from lab-scale quantum computers to truly application-focused systems could greatly accelerate the pace
