Proposed atomic cascade experimental test of symmetric local hidden-variables theories

Abstract

The proposal is made of replacing the usual auxiliary assumptions needed for the derivation of testable Bell inequalities by an assumption resting only on symmetry considerations. It is shown that reliable atomic cascade tests of symmetric local hidden-variables theories should combine high statistics, cascades of type 0→1→0, and calcite polarizers. The three conditions have been achieved in experiments already performed, but never before simultaneously.
