Experimental Realization of Teleporting an Unknown Pure Quantum State via Dual Classical and Einstein-Podolsky-Rosen Channels
D. Boschi,Salvatore Branca,F. De Martini,Lucien Hardy,Lucien Hardy,Sandu Popescu,Sandu Popescu +6 more
TL;DR: In this article, a quantum optical experimental implementation of teleportation of unknown pure quantum states was reported, which realizes all of the nonlocal aspects of the original scheme proposed by Bennett et al. and is equivalent to it up to a local operation.
Journal ArticleDOI
No signaling and quantum key distribution.
TL;DR: A key distribution scheme provably secure against general attacks by a postquantum eavesdropper limited only by the impossibility of superluminal signaling is described, which stems from violation of a Bell inequality.
Journal ArticleDOI
Nonlocality for two particles without inequalities for almost all entangled states
TL;DR: It is shown that it is possible to demonstrate nonlocality for two particles without using inequalities for all entangled states except maximally entangled states such as the singlet state.

Quantum Theory From Five Reasonable Axioms
TL;DR: In this paper, it was shown that quantum theory can be derived from very reasonable axioms, such as complex Hilbert spaces, Hermitean operators, and trace formulas for calculating probabilities.
Journal ArticleDOI
Quantum mechanics, local realistic theories, and Lorentz-invariant realistic theories.
TL;DR: Bell's theorem is demonstrated, without using inequalities, for an experiment with two particles, and it is shown that, if realism and Lorentz-invariant observables are assumed, it can derive a contradiction with quantum mechanics.
