A Classical System for Producing “Quantum Correlations”

Robert H. McEachern

Published Sep 1, 2016• 3 citations
OpenAlex

Abstract

It is almost universally supposed, that “Quantum Correlations”, as discussed in connection with Bell’s Inequality Theorem, cannot be produced by any classical, macroscopic system. Nevertheless, this paper demonstrates the actual construction of just such a system. It then discusses why this peculiar type of classical system, unlike any other, behaves in this “weird” fashion. The reason illuminates the Physics Community’s profound misunderstanding of exactly what a single, classical “bit” is, in the context of Shannon’s Information Theory, and the resulting misinterpretation of the Heisenberg Uncertainty Principle and the EPR paradox.

Resolving the EPR Paradox and Bell's Theorem

Robert H. McEachern

The EPR Paradox and the quantum correlations described by Bell's Inequality theorem, are explained as arising from the behavior of entities that manifest only a single bit of information, such as noisy, band-limited, polarized coins.

EPR inequalities: a practical tool to identify entanglement and go beyond Heisenberg uncertainty

Milena D’Angelo, Morton H. Rubin, Yanhua H. Shih

We prove the EPRs inequalities allow distinguishing (experimentally) entanglement from classical correlation in momentum and position variables for two particles/photons systems. We discuss the connection between EPR inequalities and uncertainty principle and conclude that only entanglement allows going beyond the limitations imposed by Heisenberg uncertainty on classically correlated systems.

A Fundamental Misunderstanding

Declan Traill

Quantum Mechanics claims that particles can become entangled such that there is a correlation in the detected results from EPR type experiments that cannot be explained by Classical Physics. This paper shows that the result can be fully explained by Classical Physics, and that the correlation curve for different angles between the two detectors can by reproduced when modeled this way. The model can even explain the results of the most recent supposed loophole-free Quantum Steering experiments – giving a clear violation of the Steering Inequality.

Untangling Quantum Entanglement

Jeremy L. Fellows

The phenomenon of quantum entanglement is explained in a way which is fully consistent with Einstein's Special Theory of Relativity. A subtle flaw is identified in the logic supporting the view that Bell's Inequality precludes all local hidden-variable theories, and it is shown how EPR-type experiments can be constructed to produce statistical correlation results in a purely classical manner which match exactly the predictions made by quantum theory.

Nonlocal Interconnectedness as a Fundamental Principle of Reality

Two significant principles of the 20th century are the Heisenberg uncertainty principle and the nonlocality principles of the Einstein, Podolsky, Rosen paradox [1]. Both these elements of quantum theory have major physical and philosophical implicatio like Bell’s Theorem and Space-Like Interconnect-edness and Other Collective Coherent Phenomena Involve nonlocality. We also present a discussion of the EPR paradox and other experiments that may demand a nonlocal explanation of the phenomenon they display.

Non-Locality and Quantum Theory: New Experimental Evidence

Luigi Accardi, Massimo Regoli

Starting from the late 60’s many experiments have been performed to verify the violation Bell’s inequality by Einstein-Podolsky-Rosen (EPR) type correlations. The idea of these experiments being that: (i) Bell’s inequality is a consequence of locality, hence its experimental violation is an indication of non locality; (ii) this violation is a typical quantum phenomenon because any classical system making local choices (either deterministic or random) will produce correlations satisfying this inequality. Both statements (i) and (ii) have been criticized by quantum probability on theoretical grounds (not discussed in the present paper) and the experiment discussed below has been devised to support these theoretical arguments. We emphasize that the goal of our experiment is not to reproduce classically the EPR correlations but to prove that there exist perfectly local classical dynamical systems violating Bell’s inequality. The conclusions of the present experiment are: no contradiction between quantum theory and locality can be deduced from the violation of Bell’s inequality. The Copenhagen interpretation of quantum theory becomes quite reasonable and not metaphyisic if interpreted at the light of the chameleon effect. One can realize quantum entanglement by classical computers. In section (7) we prove that our experiment also provides a classical analogue of the type of logical (i.e. independent of statistics) incompatibilities pointed out by Greenberger, Home and Zeilinger. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
