Prof Adrian Kent

Senior Advisor

Adrian Kent is Professor of Quantum Physics in the Department of Applied Mathematics and Theoretical Physics, University of Cambridge, a Distinguished Visiting Research Chair at Perimeter Institute for Theoretical Physics, and an Affiliate of the Institute for Quantum Computing in Waterloo, Ontario.

He was the first to show that relativistic signaling constraints have significant cryptographic uses, pioneering the field of relativistic quantum cryptography. With Jonathan Barrett and Lucien Hardy, he showed that quantum key distribution schemes can be proven secure based on the no-signaling principle alone, which initiated the development of device-independent quantum key distribution and quantum cryptography. Together with Roger Colbeck, he invented quantum randomness expansion. Among his other contributions is recent work, partly in collaboration with Emily Adlam, on summoning, a key task for designing quantum algorithms in space-time.
