From Wikipedia, the free encyclopedia
Artur Ekert (born 19 September 1961 in Wrocław, Poland) is a Leigh-Trapnell Professor of Quantum Physics at the Department of Applied Mathematics and Theoretical Physics, Cambridge University and a Lee Kong Chian Centennial Professor at the National University of Singapore. Ekert is one of the pioneers of quantum cryptography. In his doctoral thesis (Oxford, 1991) he showed how quantum entanglement and non-locality can be used to distribute cryptographic keys with perfect security. For his work on entanglement based quantum key distribution he was awarded the 1995 Maxwell Medal and Prize of the Institute of Physics. He is also a co-recipient of the 2004 EU Descartes Prize.
