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

The Cellular Automaton Interpretation of Quantum Mechanics. A View on the Quantum Nature of our Universe, Compulsory or Impossible?
TL;DR: In this paper, the authors argue that even the Standard Model, together with gravitational interactions, may be viewed as a quantum mechanical approach to analyse a system that could be classical at its core, and explain how these seemingly heretic thoughts can be reconciled with Bell's theorem and the usual objections voiced against the notion of super determinism.

Bell inequalities for continuous-variable correlations.
TL;DR: It is shown that above a constant detector efficiency threshold, the continuous-variable Bell violation can survive even in the macroscopic limit of large n, and can be used to derive other well-known Bell inequalities, shedding new light on the importance of non-commutativity for violations of local realism.

CHSH Inequality: Quantum Probabilities as Classical Conditional Probabilities
TL;DR: In this article, the results of observations in the EPR-Bohm-Bell experiment were described within the classical probabilistic framework, where the quantum probabilities were interpreted as conditional probabilities, where conditioning is with respect to fixed experimental settings.

Experimental single-photon exchange along a space link of 7000 km
Daniele Dequal,Giuseppe Vallone,Davide Bacco,Simone Gaiarin,Vincenza Luceri,Giuseppe Bianco,Paolo Villoresi +6 more
TL;DR: In this paper, the authors reported the single-photon exchange from a medium Earth orbit satellite (MEO) at more than $7000\phantom{\rule{0.28em}{0ex}}\text{km}$ of slant distance to the ground station at the Matera Laser Ranging Observatory.

Efficient representation of topologically ordered states with restricted Boltzmann machines
TL;DR: In this paper, restricted Boltzmann machines (RBMs) have been used to represent a wide class of many-body entangled states with rich exotic topological orders, including ground states of double semion and twisted quantum double models.

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.
