Demonstration of Temporal Distinguishability in a Four-Photon State and a Six-Photon State
arXiv:quant-ph/0602015 · doi:10.1103/PhysRevLett.97.023604
Abstract
An experiment is performed to demonstrate the temporal distinguishability of a four-photon state and a six-photon state, both from parametric down-conversion. The experiment is based on a multi-photon interference scheme in a recent discovered NOON-state projection measurement. By measuring the visibility of the interference dip, we can distinguish the various scenarios in the temporal distribution of the pairs and thus quantitatively determine the degree of temporal (in)distinguishability of a multi-photon state.
