Journal ArticleDOI
Unconditional quantum teleportation
Akira Furusawa,J. L. Sørensen,Samuel L. Braunstein,Christopher A. Fuchs,H. J. Kimble,Eugene S. Polzik +5 more
TL;DR: The first realization of unconditional quantum teleportation where every state entering the device is actually teleported is realized, using squeezed-state entanglement.
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.
Journal ArticleDOI
Cryptographic distinguishability measures for quantum-mechanical states
TL;DR: In this paper, four measures of distinguishability for quantum-mechanical states are surveyed from the point of view of the cryptographer with a particular eye on applications in quantum cryptography.
Journal ArticleDOI
Noncommuting Mixed States Cannot Be Broadcast
TL;DR: It is shown that, given a general mixed state for a quantum system, there are no physical means for broadcasting that state onto two separate quantum systems, even when the state need only be reproduced marginally on the separate systems.
Journal ArticleDOI
Optimal universal and state-dependent quantum cloning
Dagmar Bruß,David P. DiVincenzo,Artur Ekert,Christopher A. Fuchs,Chiara Macchiavello,John A. Smolin +5 more
TL;DR: The best possible approximation to a perfect quantum cloning machine that produces two clones out of a single input is established and an upper bound on the quantum capacity of the depolarizing quantum channel is derived.
