SIMPLE EXAMPLE OF NONLOCALITY - ATOMS INTERACTING WITH CORRELATED QUANTIZED-FIELDS

We present a simple example that shows nonlocality in quantum mechanics. The basic elements are two microwave cavities equipped with correlated quantized fields that interact with two atoms. We perform state-selective measurements on these atoms that subsequently reveal a type of nonlocality recently described by Hardy [Phys. Rev. Lett. 71, 1665 (1993)]. © 1995 The American Physical Society.
