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

Quantum interference and collapse of the wavefunction in cavity QED
TL;DR: In this article, the authors calculate the delayed coincidence rate for photons transmitted by a driven cavity containing N two-level atoms and show that under cavity QED conditions (strong dipole coupling) the coincidence rate shows a nonclassical dependence on delay.

TL;DR: 1,024 random bits that are uniformly distributed to within 10−12 and unpredictable assuming the impossibility of superluminal communication are generated and certified using a loophole-free Bell test and a protocol is described that is optimized for devices that are characterized by a low per-trial violation of Bell inequalities.

Contextualizing concepts using a mathematical generalization of the quantum formalism
Liane Gabora,Diederik Aerts +1 more
TL;DR: In this paper, the state context property (SCOP) formalism is used to describe the contextual manner in which concepts are evoked, used and combined to generate meaning, and two contextual measures of conceptual distance are provided, one using collapse probabilities and the other weighted properties.

Relaxed Bell inequalities and Kochen-Specker theorems
TL;DR: In this article, the authors quantified the necessary degrees of relaxation required in any model of quantum correlations via natural distance and information-theoretic measures, and showed that the existence of an outcome-independent model is equivalent to existence of a deterministic model, and the robustness of a class of Kochen-Specker theorems to relaxation of measurement independence.

Direct measurement of finite-time disentanglement induced by a reservoir
TL;DR: In this paper, a method for directly probing the dynamics of disentanglement of an initial two-qubit entangled state under the action of a reservoir is proposed, which yields an operational meaning to entanglement measures, exemplified for cavity quantum electrodynamics and trapped ions.

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.
