Abstrakt

We consider an entangled two-particle state that is produced from two independent downconversion laser sources by the process of "entanglement swapping," so that the particles have never met. We prove a Greenberger-Horne-Zeilinger type theorem, showing that any deterministic, local, realistic theory is inconsistent with the quantum-mechanical perfect correlations for such a state. This theorem holds for individual events, with no inequalities, for detectors of 100% efficiency.
