Distinguishing genuine entangled two-photon-polarization states from independently generated pairs of entangled photons
arXiv:quant-ph/0311075 · doi:10.1103/PhysRevLett.92.153602
Abstract
A scheme to distinguish entangled two-photon-polarization states (ETP) from two independent entangled one-photon-polarization states (EOP) is proposed. Using this scheme, the experimental generation of ETP by parametric down-conversion is confirmed through the anti-correlations between three orthogonal two-photon-polarization states. The estimated fraction of ETP among the correlated photon pairs is 37% in the present experimental setup.
