Adrian Kent is Professor of Qantum Physics in the Department of Applied Mathematics and Theoretical Physics and a Distinguished Visiting Research Chair at Perimeter Institute for Theoretical Physics. His research interests span the foundations of physics and technological applications of quantum information. He pioneered the use of relativistic signalling constraints in cryptography, and co-authored research that sparked the field of “device-independent” quantum cryptography, which gives users security guarantees even when their devices may have been designed by a malicious supplier. More recently, he has developed “supermoney”, a form of token that gives users privacy and issuers security against fraud and is faster and more flexible than any existing technology. He has a strong interest in how we most effectively channel science and technological developments to shape our future in positive directions and to reduce catastrophic threats, and is a member of the scientific advisory board of the Cambridge Centre for the Study of Existential Risk.
