Raczynski et al., NIMA 786 (2015) International Patent Applications Jagiellonian PET σ(t-hit) = 80 ps It is an open question whether or not the three-photon entanglement can be reduced to the two- photon entanglement and decoherence of the two-photon states does imply decoherence in photon triplets. This hypothesis can be tested by comparison of measured two- and three-photon correlation functions. There exist three-photon states maximizing the GHZ entanglement and they can be used to test quantum local realism versus quantum mechanics.
