Failure of Bell’s Theorem and the Local Causality of the Entangled Photons

چکیده

A counterexample to Bell’s theorem is presented which uses a pair of photons instead of spin-1/2 particles used in our previous counterexamples. A locally causal protocol is provided for Alice and Bob, which allows them to simulate observing photon polarizations at various angles, and record their results as A = ± 1 ∈ S and B = ± 1 ∈ S, respectively. When these results are compared, the correlations are seen to be exactly those predicted by quantum mechanics; namely cos 2(α− β), where α and β are the angles of polarizers. The key ingredient in our counterexample is the topology of 3-sphere, which remains closed under multiplication, thus preserving the locality condition of Bell.

Disproof of Bell’s Theorem: Further Consolidations

The failure of Bell’s theorem for Clifford algebra valued local variables is further consolidated by proving that the conditions of remote parameter independence and remote outcome independence are duly respected within the recently constructed exact, local realistic model for the EPR-Bohm correlations. Since the conjunction of these two conditions is equivalent to the locality condition of Bel...

Lab1: Entanglement and Bell’s Inequalities

In this laboratory, entanglement as one of the key concepts in quantum mechanics was introduced, and we concentrated on the polarized entangled photons. Bell’s inequality was used as a criterion of quantum and classic. The polarized entangled photons were created by Spontaneous Parametric Down-Conversion in Beta Barium Borate crystals. The coincidence counts were measured as the number of entan...

It is generally believed that Bell’s inequality holds for the case of entangled states, including two correlated particles or special states of a single particle. Here, we derive a single-particle Bell’s inequality for a non-entangled spin state, appealing to the statistical independence condition of a locally causal hidden variable theory. We show that regardless of the locality assumption, th...

Two new formulations of Bell’s theorem are given here. First, we consider a definite set of two entangled photons with only two polarization directions, for which Bell’s locality assumption is violated for the case of perfect correlation. Then, using a different approach, we prove an efficient Bell-type inequality which is violated by some quantum mechanical predictions, independent of the effi...

Entanglement and Bell’s Inequalities

Our goal for this experiment was to demonstrate violation of Bell’s inequalties. This was accomplished by producing two polarization entangled photons via spontaneous parametric down-conversion using two type 1 beta barium borate crystals. With polarizers placed in front of two avalanche photodiodes, we observed how the alignment of the polarizers affected the number of observed photon pairs co...
