TLDR
In this article, it was shown that even without such a separability or locality requirement, no hidden variable interpretation of quantum mechanics is possible and that such an interpretation has a grossly nonlocal structure, which is characteristic of any such theory which reproduces exactly the quantum mechanical predictions.Abstract:
THE paradox of Einstein, Podolsky and Rosen [1] was advanced as an argument that quantum mechanics could not be a complete theory but should be supplemented by additional variables These additional variables were to restore to the theory causality and locality [2] In this note that idea will be formulated mathematically and shown to be incompatible with the statistical predictions of quantum mechanics It is the requirement of locality, or more precisely that the result of a measurement on one system be unaffected by operations on a distant system with which it has interacted in the past, that creates the essential difficulty There have been attempts [3] to show that even without such a separability or locality requirement no "hidden variable" interpretation of quantum mechanics is possible These attempts have been examined elsewhere [4] and found wanting Moreover, a hidden variable interpretation of elementary quantum theory [5] has been explicitly constructed That particular interpretation has indeed a grossly nonlocal structure This is characteristic, according to the result to be proved here, of any such theory which reproduces exactly the quantum mechanical predictionsread more

Building quantum wires: the long and the short of it
TL;DR: This paper introduces a quantum wire architecture based upon quantum teleportation and compares this teleportation channel with the traditional approach to transporting quantum data, which is referred to as the swapping channel, and describes how the advanced architecture of the teleportation channel overcomes a basic limit to the maximum communication distance of the swaps channel.

Coherent ultrafast measurement of time-bin encoded photons.
TL;DR: A tomographically complete set of time-bin qubit projective measurements is demonstrated and the fidelity of operations is sufficiently high to violate the Clauser-Horne-Shimony-Holt-Bell inequality by more than 6 standard deviations.

Multipartite bound entangled states that violate Bell's inequality.
Wolfgang Dür,Wolfgang Dür +1 more
TL;DR: It is proved that there exist multipartite bound entangled states (i.e., nonseparable, nondistillable states) that violate a multipartsite Bell inequality, which implies that (i) violation of Bell's inequality is not a sufficient condition for distillability and (ii) some bound entangledStates cannot be described by a local hidden variable model.

Steering bound entangled States: a counterexample to the stronger Peres conjecture.
TL;DR: A method is provided to generate systematically bound entangled quantum states which can still be used for steering and, therefore, to rule out local hidden state models and sheds light on the relations between the various views on quantum correlations.
Journal ArticleDOI
The nonclassical light
TL;DR: In this article, a systematic operational approach is presented to study the nonclassical light (NCL) using two parallel sets of numbers measured: probabilities of photocounts and normalised factorial moments of counts.

Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?
TL;DR: Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that one is led to conclude that the description of reality as given by a wave function is not complete.

Discussion of Experimental Proof for the Paradox of Einstein, Rosen, and Podolsky
D. Bohm,Yakir Aharonov +1 more
TL;DR: A brief review of the physical significance of the paradox of Einstein, Rosen, and Podolsky is given, and it is shown that it involves a kind of correlation of the properties of distant noninteracting systems, which is quite different from previously known kinds of correlation as discussed by the authors.
