Abstract
We present recent progress in the implementation of experimental realization of a loophole-free test of Bell inequalities for entangled 111Cd atoms. The experimental approach is a modified version of the proposal of Fry and co-workers (Phys. Rev. A 52(6), 1995, p. 4381) for the re-alization of Bohm’s 1/2-spin particle version of the Einstein–Podolsky–Rosen (E-P-R) experiment and is based on the production of entangled atoms by photodissociation of the 111Cd2 isotopologue in a supersonic expansion beam using the spectroscopically selective stimulated Raman process.
