    This is a question about a slightly modified version of the EPR experiment:

    The experiment requires:
    A source of entangled positron pairs
    A source of entangels electron pairs
    A pair of Stein-Gerlach type spin orientation detectors.

    Let's say that there is a linear arrangement of
    Detector - Positron source - Annihillation Chamber - Electron Source - Detector

    And, I try to measure correlation between spin states of the electron at one end, and the positron at the other in a fashion similar to that of the EPR experiment.

    Does QM - if it matters let's say the Copenhagen interpretation - indicate that there will be spin corellation between the pairs?

    This experiment is interesting to me because it creates a situation where Bell's theorem may not be necessary to eliminate locality. Since any 'synconization pulse' would have to have taken place before the electron/postitron pair came into existance. On the other hand, AFAIK, the products of the Positron/Electron interaction have net spin zero, so a lack of correlation would indicate a violation of conservation of spin/angular momentum.
