    "abstract": "Two schemes of projection measurement are realized experimentally to\ndemonstrate the de Broglie wavelength of three photons without the need for a\nmaximally entangled three-photon state (the NOON state). The first scheme is\nbased on the proposal by Wang and Kobayashi (Phys. Rev. A {\\bf 71}, 021802)\nthat utilizes a couple of asymmetric beam splitters while the second one\napplies the general method of NOON state projection measurement to three-photon\ncase. Quantum interference of three photons is responsible for projecting out\nthe unwanted states, leaving only the NOON state contribution in these schemes\nof projection measurement.",
