Journal ArticleDOI

Mixed State Entanglement and Quantum Error Correction

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.

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

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

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.
