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…
Inferring superposition and entanglement from measurements in a single basis
Bella Schelpe, Adrian Kent, William Munro +1
We discuss what can be inferred from measurements on one- and two-qubit systems using a single measurement basis at various times. We show that, given reasonable physical assumptio…
Quantum nonlocality, Bell inequalities and the memory loophole
Jonathan Barrett, Daniel Collins, Lucien Hardy +2
In the analysis of experiments designed to reveal violation of Bell-type inequalities, it is usually assumed that any hidden variables associated with the nth particle pair would b…
Nonlinearity without Superluminality
Adrian Kent
Quantum theory is compatible with special relativity. In particular, though measurements on entangled systems are correlated in a way that cannot be reproduced by local hidden vari…
Causal Quantum Theory and the Collapse Locality Loophole
Adrian Kent
Causal quantum theory is an umbrella term for ordinary quantum theory modified by two hypotheses: state vector reduction is a well-defined process, and strict local causality appli…
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 ``…
