Journal ArticleDOI
Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels
Charles H. Bennett,Gilles Brassard,Claude Crépeau,Richard Jozsa,Asher Peres,William K. Wootters +5 more
TL;DR: An unknown quantum state \ensuremath{\Vert}\ensure Math{\varphi}〉 can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-Rosen (EPR) correlations.
Journal ArticleDOI
Rapid Solution of Problems by Quantum Computation
David Deutsch,Richard Jozsa +1 more
TL;DR: A class of problems is described which can be solved more efficiently by quantum computation than by any classical or stochastic method.
Journal ArticleDOI
Fidelity for Mixed Quantum States
TL;DR: In this article, the authors propose a definition of fidelity for mixed quantum states in terms of Uhlmann's transition probability formula F(ϱ1, ϱ2) = {trace [(√ϱ 1ϱ2 × √ ϱ 1)1/2]}2 and give new elementary proofs of its essential properties.
Journal ArticleDOI
Quantum Computation and Shor's Factoring Algorithm
Artur Ekert,Richard Jozsa +1 more
TL;DR: The authors give an exposition of Shor's algorithm together with an introduction to quantum computation and complexity theory, and discuss experiments that may contribute to its practical implementation.
Journal ArticleDOI
Quantum Privacy Amplification and the Security of Quantum Cryptography over Noisy Channels
TL;DR: The concept of quantum privacy amplification and a cryptographic scheme incorporating it which is provably secure over a noisy channel is introduced and implemented using technology that is currently being developed.
