Unitary representations of the Virasoro and super-Virasoro algebras

P. Goddard, A. Kent, D. Olive
Mathematics
1986

It is shown that a method previously given for constructing representations of the Virasoro algebra out of representations of affine Kac-Moody algebras yields the full discrete series of highest… Expand

Virasoro algebras and coset space models

P. Goodard, A. Kent, D. Olive
Physics
28 February 1985

Abstract A previous construction of unitary representations of the Virasoro algebra is extended and interpreted physically in terms of a coset space quark model. The quaternionic projective spaces… Expand

Many worlds? : Everett, quantum theory, and reality

S. Saunders, J. Barrett, A. Kent, D. Wallace
Mathematics
2010

Many Worlds: an Introduction 1. WHY MANY WORLDS? 1. Decoherence and Ontology 2. Quasiclassical Realms 3. Macroscopic Superpositions, Decoherent Histories, and the Emergence of Hydrodynamical… Expand

No signaling and quantum key distribution.

J. Barrett, L. Hardy, A. Kent
Physics, Computer Science
Physical review letters
18 May 2004

We propose a quantum key distribution protocol that is provably secure against general attacks by a postquantum eavesdropper limited only by the impossibility of superluminal signaling. Expand

Private randomness expansion with untrusted devices

R. Colbeck, A. Kent
Computer Science, Physics
19 November 2010

We introduce a protocol for private randomness expansion with untrusted devices which is designed to take as input an initially private string and produce as output a longer private random string. Expand

On the consistent histories approach to quantum mechanics

Fay Dowker, A. Kent
Mathematics, Physics
22 December 1994

We review the consistent histories formulations of quantum mechanics developed by Griffiths, Omnès, and Gell-Mann and Hartle, and describe the classification of consistent sets. We illustrate some… Expand

Determinant Formulae and Unitarity for the N=2 Superconformal Algebras in Two-Dimensions or Exact Results on String Compactification

W. Boucher, D. Friedan, A. Kent
Physics
22 May 1986

Determinant formulae are presented for the periodic, antiperiodic and twisted N = 2 superconformal algebras in two dimensions, and a classification is derived of the unitary highest weight… Expand

Memory attacks on device-independent quantum cryptography.

J. Barrett, R. Colbeck, A. Kent
Computer Science, Physics
Physical review letters
20 January 2012

We identify a critical weakness of device-independent protocols that rely on public communication between secure laboratories. Expand

Cheat sensitive quantum bit commitment.

L. Hardy, A. Kent
Computer Science, Medicine
Physical review letters
9 November 1999

We define cheat sensitive cryptographic protocols between mistrustful parties as protocols which guarantee that, if either cheats, the other has some nonzero probability of detecting the cheating. Expand

One world versus many: the inadequacy of Everettian accounts of evolution, probability, and scientific confirmation

A. Kent
Physics, Mathematics
5 May 2009

There is a compelling intellectual case for exploring whether purely unitary quantum theory defines a sensible and scientifically adequate theory, as Everett originally proposed. Many different and… Expand
