Proposed Experiment to Test Local Hidden-Variable Theories

JCJohn F. ClauserMHMichael HorneASAbner Shimony

Key Points

  • Generalize Bell's theorem to develop a feasible, real-world experimental design capable of testing quantum mechanical predictions against local hidden-variable theories.
  • Generalized the mathematical formulation of Bell's theorem to apply directly to realizable laboratory measurements.
  • Formulated an experimental proposal extending the Kocher-Commins apparatus to measure the polarization correlation between pairs of optical photons.
  • Demonstrated that generalized Bell-type inequalities can be empirically evaluated using optical photon pair polarization correlations.
  • Provided a concrete experimental framework designed to decisively rule out either quantum mechanics or the full class of local hidden-variable theories.

Abstract

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.
