Paper Abstract

A scheme to distinguish entangled two-photon-polarization states (ETP) from two independent it entangled one-photon-polarization states 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.
