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

Experimental Quantification of Asymmetric Einstein-Podolsky-Rosen Steering.
Kai Sun,Xiang Jun Ye,Jin-Shi Xu,Xiao Ye Xu,Jian Shun Tang,Yu-Chun Wu,Jing Ling Chen,Jing Ling Chen,Chuan-Feng Li,Guang-Can Guo +9 more
TL;DR: This work experimentally demonstrate asymmetric EPR steering for a class of two-qubit states in the case of two measurement settings and provides new insight into the fundamental asymmetry of quantum nonlocality and has potential applications in asymmetric quantum information processing.

Realism and the physical world
TL;DR: In this article, the applicability of the concept of classical realism is constrained by existing experiments both in the EPR-Bell setup, including recent experiments testing "nonlocal realistic" theories, and in the area of "macroscopic quantum coherence".

Orbital entanglement and violation of Bell inequalities in mesoscopic conductors.
TL;DR: It is shown that the Bell inequality can be violated for arbitrary strong dephasing in the normal conductor.

Atomic Hong–Ou–Mandel experiment
Raphael Lopes,Almazbek Imanaliev,Alain Aspect,Marc Cheneau,Denis Boiron,Christoph I Westbrook +5 more
TL;DR: This work reports the realization of the Hong, Ou and Mandel experiment using atoms instead of photons, and opens the way to testing Bell's inequalities involving mechanical observables of massive particles, such as momentum, using methods inspired by quantum optics, and to testing theories of the quantum-to-classical transition.

On schizophrenic experiences of the neutron or why we should believe in the many‐worlds interpretation of quantum theory
TL;DR: In this paper, the concept of the measure of existence of a world is introduced and some difficulties with the issue of probability in the framework of the many-world interpretation of quantum theory are resolved.

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.
