Variable Bias Coin Tossing
Roger Colbeck, Adrian Kent
Alice is a charismatic quantum cryptographer who believes her parties are unmissable; Bob is a (relatively) glamorous string theorist who believes he is an indispensable guest. To…
Noncontextuality, Finite Precision Measurement and the Kochen-Specker Theorem
Jonathan Barrett, Adrian Kent
Meyer recently queried whether non-contextual hidden variable models can, despite the Kochen-Specker theorem, simulate the predictions of quantum mechanics to within any fixed fini…
Large N Quantum Cryptography
Adrian Kent
In quantum cryptography, the level of security attainable by a protocol which implements a particular task times bears no simple relation to the level of security attainable by…
Locality and reality revisited
Adrian Kent
Bell gave the now standard definition of a local hidden variable theory and showed that such theories cannot reproduce the predictions of quantum mechanics without violating his ``…
Quantum Interrogation and the Safer X-ray
Adrian Kent, David Wallace
We investigate quantum interrogation techniques which allow imaging information about semi-transparent objects to be obtained with lower absorption rates than standard classical me…
Secure Classical Bit Commitment using Fixed Capacity Communication Channels
Adrian Kent
If mutually mistrustful parties A and B control two or more appropriately located sites, special relativity can be used to guarantee that a pair of messages exchanged by A and B ar…
