A local hidden-variable model based on `isolato' hypothesis of the EPR--Bohm Gedanken experiment is presented. The `isolato' hypothesis states that one of a pair of spin- ${1}/{2}$ particles can be in `isolato' mode in which the spin- ${1}/{2}$ particle shuts itself from any external interactions, and hence it can never be detected. As a result of this, data rejection is made; Bell's inequality is violated, although the model is genuinely local. In this model, $2/\\pi$ ( $\\simeq$ 63.6%) of the initially prepared ensemble of pairs of spin- ${1}/{2}$ particles are detected as a pair of particles, and others are detected as a single particle. This does not disagree with the results of the experiments performed before, since these single spin- ${1}/{2}$ particles were regarded as noise.A local hidden-variable model based on `isolato' hypothesis of the EPR--Bohm Gedanken experiment is presented.

On a local hidden-variable model with ‘isolato’ hypothesis of the EPR-Bohm Gedanken experiment

Satoshi Uchiyama

A local hidden‐variable model based on ‘isolato’ hypothesis of the EPR‐Bohm Gedanken experiment is presented. The ‘isolato’ hypothesis states that one of a pair of spin‐1/2 particles can be in ‘isolato’ mode in which the spin‐1/2 particle shuts itself from any external interactions, and hence it can never be detected. As a result of this, data rejection is made; Bell’s inequality is violated, although the model is genuinely local. In this model, 2/π (≃ 63.6%) of the initially prepared ensemble of pairs of spin‐1/2 particles are detected as a pair of particles, and others are detected as a single particle. This does not disagree with the results of the experiments performed before, since these single spin‐1/2 particles were regarded as noise.A local hidden‐variable model based on ‘isolato’ hypothesis of the EPR‐Bohm Gedanken experiment is presented.

On Some Aspects of an Hg Based EPR Experiment

Thomas Walther, Edward S. Fry

Abstract An experimental realization of Bohm's spin-1/2 EPR gedanken-experiment is possible using the spin-1/2 nuclei of the isotope 199 Hg. The dissociation of dimers of the 199 Hg 2 isotopomer, using a spectroscopically selective stimulated Raman process, leads to the generation of an entangled state between the two 199 Hg atoms. The measurement of nuclear spin correlations between the two atoms in this entangled state is achieved by detection of the atoms using a spin state selective two photon excitation-ionization scheme. The experiment will not only close the detector efficiency loophole, but in addition will permit enforcement of the locality condition. Effects of imperfect analyzers will also be discussed.Abstract An experimental realization of Bohm's spin-1/2 EPR gedanken-experiment is possible using the spin-1/2 nuclei of the isotope 199 Hg.
