    "abstract": "A scheme to distinguish entangled two-photon-polarization states (ETP) from\ntwo independent entangled one-photon-polarization states (EOP) is proposed.\nUsing this scheme, the experimental generation of ETP by parametric\ndown-conversion is confirmed through the anti-correlations between three\northogonal two-photon-polarization states. The estimated fraction of ETP among\nthe correlated photon pairs is 37% in the present experimental setup.",
