Wave Plates and Entanglement

  1. Jan 26, 2012 #1
    If we produce a three-pair of entangled photons, and send two of them towards polarising beam splitters, and one towards a vertically aligned wave plate - according to QM we need to describe the photon as being in a superposition of V and H when they hit the beam splitters, but when the photon hits the wave plate - is that the one that makes the measurement, and we'll find that the V polarised photon of the entangled photons coming from the wave plate (the others taking on H polarisations). In comparison, if collapse occured at either of the polarisers (perhaps delaying the time the photon reaches the wave plate), we might see a V polarised photon at one of the beam splitters?
