An Experiment Showing Entanglement Communication into the Future

  1. Jul 31, 2011 #1
    I recently have been doing some work on the entanglement phenomenon. In this regard someone brought to my attention an experiment with amazing results but unfortunately he did not have an exact reference for the experimenter or where the results were published. Very briefly, the experimenter created two entangled particles and using acoustic waves shifted the time clock on both particles so that each was time-wise ahead of the other particle. How, he reasoned, under this scenario could it be possible, even if somehow the particles could communicate, that they could act entangled? Each particle got to the threshold first so there is no way it could “know”, even if it could communicate, what the other particle was going to do! To everyone’s amazement the two particles acted as “one”. If you knew what one particle did you knew what the other one did – 100% of the time with no exceptions.
    Is anyone familiar with this experiment? Can you help me with who the experimenter(s) was and when and where the results were first published?

    That was not acoustics, but macroscale (rotating disc of the size of gramophone plate) movement.
    Set of before-before Aspect's like experiments (each detector is first in his own frame) had been performed by Geneva University group led by N.Gisin. See for example
    http://arxiv.org/abs/quant-ph/0002031v3 (and follow it's references)

    Theoretically, For making an entangled state, at first we have to make an "interaction" between the particles such as electrons, etc., i.e. we have to add a potential (between our particles) in our Hamiltonian, otherwise the state of our system is a multiple of state of single particles and so no correlation during every kind of measurement, which equals to no entangled state. It can be understood clearly when we look at Schrodinger's equation.

    I'm sorry. I send my message in wrong section.
