    "abstract": "We experimentally study two-photon coherence in plasmon-assisted transmission\nwith a two-photon Mach-Zehnder (MZ) interferometer. Two collinear photons of\nidentical or orthogonal polarization are simultaneously incident on one\noptically thick metal film, perforated with a periodic array of subwavelength\nholes. The de Broglie wavelength of plasmon-assisted transmitted photons is\nmeasured, which shows that two photons are re-eradiated by the plasmons and the\nquantum coherence of biphoton is preserved in the conversion process of\ntransforming biphoton to plasmons and then back to biphoton.",
