    "abstract": "An experiment is performed to demonstrate the temporal distinguishability of\na four-photon state and a six-photon state, both from parametric\ndown-conversion. The experiment is based on a multi-photon interference scheme\nin a recent discovered NOON-state projection measurement. By measuring the\nvisibility of the interference dip, we can distinguish the various scenarios in\nthe temporal distribution of the pairs and thus quantitatively determine the\ndegree of temporal (in)distinguishability of a multi-photon state.",
