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 phase-programmable Gaussian boson sampling (GBS) was used to produce photon detection events out of a 144-mode photonic circuit, and the obtained samples are efficiently validated by inferring from computationally friendly subsystems.

Guess your neighbor's input: A multipartite nonlocal game with no quantum advantage
Mafalda L. Almeida,Jean-Daniel Bancal,Nicolas Brunner,Antonio Acín,Nicolas Gisin,Stefano Pironio +5 more
TL;DR: The results suggest that quantum correlations might obey a generalization of the usual no-signaling conditions in a multipartite setting, and identify parts of the boundary between quantum and postquantum correlations of maximal dimension.

Quantum physics of simple optical instruments
TL;DR: In this paper, the quantum theory of simple optical instruments is developed and applied to a few characteristic situations, such as splitting and interference of photons and the manifestation of Einstein-Podolsky-Rosen correlations in parametric downconversion.

Decision Theory with Prospect Interference and Entanglement
TL;DR: It is demonstrated how the violation of the Savage’s sure-thing principle, known as the disjunction effect, can be explained quantitatively as a result of the interference of intentions, when making decisions under uncertainty.

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.
