Experimental tests of quantum mechanics versus local hidden variable theories

Abstract

The authors propose new inequalities involving polarisation correlation parameters as tests of local hidden variable theories versus quantum mechanics. These are derived using Bell's formulation of Einstein's locality condition.

A Critical Review of the Experimental Tests of Bell's Inequalities

Huang Zheng-xin

Bell's inequalities(1964) provides a quantitative criterion to test the local hidden variable theory(LHVT) versus quantum mechanics(QM).For the first time,it leads to the possibility to experimentally distinguish LHVT and QM.So far,there have been tens of experiments ever since the first experiment by Clauser et al(1972).An overwhelming majority of these experiments are in good agreement with the predictions of QM yet violate those of LHVT.Some loopholes in these experiments are discussed in Section I,followed by a respective summary to 12 experiments between 1972 to 1982 and 31 experiments from 1985 and on in Sections II and III.It is finally pointed out that so far there is not a single experiment to close both the locality loophole and the detection loophole at the same time,but the experimental outcomes are irreversible.Accordingly,theoretical physicists must admit that the present physics foundation is broken,i.e.quantum mechanics is contradiction with special relativity.

Experimental test of the predictions of the local hidden variable theories

Mohammad LAMEHI-RACHTI, W. Mittig

Bell showed (''Bell's inequality) that local hidden variable theories lead to predictions in contradiction with quantum mechanics. This was tested in low energy proton-proton scattering by the simultaneous measurement of the polarization of the two protons. The results are in agreement with quantum mechanics and thus in contradiction with the inequality of Bell. (FR)

Experimental Test of Local Hidden-Variable Theories

S. J. Freedman, John F. Clauser

We have measured the linear polarization correlation of the photons emitted in an atomic cascade of calcium. It has been shown by a generalization of Bell's inequality that the existence of local hidden variables imposes restrictions on this correlation in conflict with the predictions of quantum mechanics. Our data, in agreement with quantum mechanics, violate these restrictions to high statistical accuracy, thus providing strong evidence against local hidden-variable theories.

Bell inequality for position and time

J. D. Franson

The quantum-mechanical uncertainty in the position of a particle or the time of its emission is shown to produce observable effects that are inconsistent with any local hidden-variable theory. A new experimental test of local hidden-variable theories based on optical interference is proposed.

Proposed Experiment to Test Local Hidden-Variable Theories

John F. Clauser, Michael Horne, Abner Shimony +1 more

A theorem of Bell, proving that certain predictions of quantum mechanics are inconsistent with the entire family of local hidden-variable theories, is generalized so as to apply to realizable experiments. A proposed extension of the experiment of Kocher and Commins, on the polarization correlation of a pair of optical photons, will provide a decisive test between quantum mechanics and local hidden-variable theories.

Local Hidden Variable Theory of Quantum Mechanics that Violates Bell's Inequality

Henok Tadesse

In this paper the mystery of local hidden variable theory of quantum mechanics that violates Bell’s inequality is proposed. These ‘hidden variables’ are fundamentally inaccessible to physical experiments. It is not something physicists ever dreamed of.
