The results of local measurements on some composite quantum systems cannot be reproduced classically. This impossibility, known as quantum nonlocality, represents a milestone in the foundations of qua...
Optimal Protocols for Nonlocality Distillation
Nonlocality Nonlocal Boxes NLBs Distillation Quantum Information
2010/10/19
Forster, Winkler, and Wolf recently showed that weak nonlocality can be amplified by giving the
first protocol that distills a class of nonlocal boxes (NLBs) [Phys. Rev. Lett. 102, 120401 (2009)].We ...
Deriving Bell's nonlocality from nonlocality at detection
Deriving Bell nonlocality nonlocality detection
2010/10/18
It is argued that Bell’s nonlocality is a particular case of nonlocality at detection, which appears already in single-particle interference experiments. The unity of nonlocality and local causality i...
Svetlichny's inequality and genuine tripartite nonlocality in three-qubit pure states
Svetlichny's inequality genuine tripartite nonlocality three-qubit pure states
2010/4/7
The violation of the Svetlichny's inequality (SI) [Phys. Rev. D, 35, 3066 (1987)] is sufficient but not necessary for genuine tripartite nonlocal correlations. Here we quantify the relationship betwee...
Quantum Mechanics and Nonlocality: In Search of Instructive Description
Quantum Mechanics Nonlocality Instructive Description
2010/4/12
A problem with an instructive description of measurement process for sufficiently separated entangled quantum systems is well known. More precise and crafty experiments together with new technological...
Classification and quantification of nonlocality in ensembles consisting of orthogonal bipartite states
Classification quantification ensembles consisting orthogonal bipartite states
2010/4/8
An ensemble of mutually orthogonal multipartite states may not be distinguishable by means of local operations and classical communication (LOCC) and could exhibit a kind of nonlocality different from...
Classical Interaction Cannot Replace Quantum Nonlocality
Classical Interaction Quantum Nonlocality
2010/4/8
We present a two-player communication task that can be solved by a protocol of polylogarithmic cost in the simultaneous message passing model with classical communication and shared entanglement, but ...
Entanglement and nonlocality of a single relativistic particle
Entanglement nonlocality relativistic particle
2010/4/8
Recent work has argued that the concepts of entanglement and nonlocality must be taken seriously even in systems consisting of only a single particle. These treatments, however, are nonrelativistic an...
There is no spooky action-at-a-distance in quantum correlations: Resolution of the EPR nonlocality puzzle
spooky action-at-a-distance quantum correlations: Resolution EPR nonlocality puzzle
2010/10/18
The long-standing puzzle of the nonlocal Einstein-Podolsky-Rosen correlations is resolved. The correct quantum mechanical correlations arise for the case of entangled particles when strict locality is...
