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, the authors show that the trajectories seem surreal only if one ignores their manifest nonlocality, which is called Bohmian mechanics, which predicts trajectories that were at first deemed “surreal” when the second particle is used to probe the position of the first particle.

Entanglement swapping between photons that have never coexisted.
TL;DR: The generated and fully characterized an entangled pair of photons that have never coexisted, and the observed two-photon state demonstrates that entanglement can be shared between timelike separated quantum systems.

Causal and causally separable processes
TL;DR: In this paper, Oreshkov, Costa, Brukner, and O'Neill developed rigorous notions of causality and causal separability in the process framework, which describes correlations between separate local experiments without a prior assumption of causal order between them.

Ensemble interpretations of quantum mechanics. A modern perspective
Dipankar Home,M.A.B. Whitaker +1 more
TL;DR: In this paper, a discussion of aspects of probability relevant to the differing interpretations of quantum theory is given, followed by an account of so-called orthodox interpretations of the quantum theory that stresses their flexibility and subtlety as well as their problems.

Optical Angular Momentum

TL;DR: In this article, the basic concepts of spin and orbital angular momentum, their connectedness through vector beams, and Poincare sphere representations of optical angular momentum carrying fields and reviews the present state of the field and its many opportunities for advancement are discussed.

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.
