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

TL;DR: In this article, a light source for producing entangled multiphoton states and measurement technologies for precise timing and efficient detection were developed, and the classical bound of the three-particle Mermin inequality was violated by nine standard deviations by closing both the locality and freedom-of-choice loopholes.

Quantum effects in optomechanical systems
TL;DR: In this article, the authors give an overview of two important topics within this research field: cooling to the motional ground state, and the generation of entanglement involving mechanical, optical and atomic degrees of freedom.

Optimal randomness certification in the quantum steering and prepare-and-measure scenarios
TL;DR: This work finds the optimal method to quantify the amount of local or global randomness that can be extracted in two scenarios: (i) the quantum steering scenario, where two parties measure a bipartite system in an unknown state but one of them does not trust his measurement apparatus, and (ii) the prepare-and-measure scenario,where additionally the quantum state is known.

Generic Bell inequalities for multipartite arbitrary dimensional systems.
TL;DR: A large set of variants are shown to naturally emerge from the generic Bell inequalities that are violated for all the systems including odd dimensional systems.

The set of quantum correlations is not closed
TL;DR: In particular, the authors showed that the set of (tensor-product) quantum correlations is not closed, and that it is undecidable to determine if a linear system game can be played perfectly with a finite-dimensional strategy, or a limit of finite dimensional quantum strategies.

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.
