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 predictions

Entangled Bloch spheres: Bloch matrix and two-qubit state space

TL;DR: In this paper, a two-qubit density matrix in the basis of Pauli matrix tensor products is represented as two entangled Bloch spheres with superimposed correlation axes, analogous to the single qubit Bloch vector.

Guaranteed violation of a Bell inequality without aligned reference frames or calibrated devices

TL;DR: Generic quantum nonlocality is demonstrated with randomly chosen measurements on a singlet state of two photons, implemented using a reconfigurable integrated optical waveguide circuit, demonstrating the robustness of these schemes to imperfections and statistical noise.

Interpretations of Quantum Theory: A Map of Madness

TL;DR: In this article, the authors argue that the interpretations of quantum theory are, essentially, of two types and that these two types are so radically different that there must be experiments that, when analyzed outside the framework of quantum theories, lead to different empirically testable predictions.

Quantum mechanics of 4-derivative theories

TL;DR: A renormalizable theory of gravity is obtained if the dimension-less 4-derivative kinetic term of the graviton admits a sensible quantization, and the resulting theory has positive energy eigenvalues, normalizable wavefunctions, unitary evolution in a negative-norm configuration space.

Near-Optimal and Explicit Bell Inequality Violations

TL;DR: In this article, the authors give two new two-player games with Bell inequality violations that are stronger, fully explicit, and arguably simpler than earlier work, and they show that the winning probability of any classical strategy differs from 1/2 by at most O(log(n)/sqrt(n)).

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

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.
