When I look at certain experiments involving entangled photons generated by spdc, for example quantum eraser experiments, it seems to me that each observed pair of entangled photons is propagated in a horizontal plane. However, aren't the entangled photons generated randomly in all planes, sometimes vertically as well as sometimes horizontally and at all angles between the vertical and horizontal? If so are all angles remote from the horizontal just eliminated from observations by virtue of the coincidence methods used. Or could it be that the system used to create the photons is prepared in such a way that the horizontal plane is the most likely?
Thanks for any replies.
