Adrian Kent

Adrian Kent is a British theoretical physicist. He is a professor at the University of Cambridge, member of the Centre for Quantum Information and Foundations, and Distinguished Visiting Research Chair at the Perimeter Institute for Theoretical Physics. His research focuses on quantum foundations, quantum information science, and quantum cryptography. In 1999 he published the first information-theoretically secure protocols for bit commitment and coin flipping, which were also the first relativistic cryptographic protocols. He is a co-inventor of quantum tagging, or quantum position authentication, providing the first schemes for position-based quantum cryptography. In 2005 he published with Lucien Hardy and Jonathan Barrett the first security proof of quantum key distribution based on the no-signalling principle.
