Interpretation of "non-local" experiments using disentanglement

Abstract

It is shown that a number of experiments designed to use entangled photon pairs in order to demonstrate the viability of quantum "teleportation" can, in fact, also be understood using disentanglement. Whether entangled or not, using an ensemble approach, the experiments can be explained without any non-local communication between Alice's photon and Bob's photon. Moreover, it is emphasized that entanglement maintains a symmetry property between the two photons that is absent in disentanglment, the symmetry being parity due to phase conerence.
