TL;DR: It is proved that an EPP involving one-way classical communication and acting on mixed state M (obtained by sharing halves of Einstein-Podolsky-Rosen pairs through a channel) yields a QECC on \ensuremath{\chi} with rate Q=D, and vice versa, and it is proved Q is not increased by adding one- way classical communication.
Journal ArticleDOI
Elementary gates for quantum computation.
Adriano Barenco,Charles H. Bennett,Richard Cleve,David P. DiVincenzo,Norman Margolus,Peter W. Shor,Tycho Sleator,John A. Smolin,Harald Weinfurter +8 more
TL;DR: U(2) gates are derived, which derive upper and lower bounds on the exact number of elementary gates required to build up a variety of two- and three-bit quantum gates, the asymptotic number required for n-bit Deutsch-Toffoli gates, and make some observations about the number of unitary operations on arbitrarily many bits.
Journal ArticleDOI
Purification of Noisy Entanglement and Faithful Teleportation via Noisy Channels
Charles H. Bennett,Gilles Brassard,Sandu Popescu,Benjamin Schumacher,John A. Smolin,William K. Wootters +5 more
TL;DR: Upper and lower bounds on the yield of pure singlets ($\ket{\Psi^-}$) distillable from mixed states $M$ are given, showing $D(M)>0$ if $\bra{Psi-}M\ket-}>\half$.
Book ChapterDOI
Experimental quantum cryptography
TL;DR: Initial results from an apparatus and protocol designed to implement quantum public key distribution are described, by which two users exchange a random quantum transmission, consisting of very faint flashes of polarized light, which remains secure against an adversary with unlimited computing power.
Journal ArticleDOI
Quantum nonlocality without entanglement
Charles H. Bennett,David P. DiVincenzo,Christopher A. Fuchs,Tal Mor,Eric M. Rains,Peter W. Shor,John A. Smolin,William K. Wootters +7 more
TL;DR: In this paper, it was shown that there is a finite gap between the mutual information obtainable by a joint measurement on these states and a measurement in which only local actions are permitted.
