    "abstract": "The two photon interference phenomenon is theoretically investigated for the\ngeneral situations with an arbitrary input two photon state with and without\nphoton polarization. For the case without polarization, the\nnecessary-sufficient condition for the destructive interference of coincidence\ncounting is given as the symmetric pairing of photons in the light pulses. For\nboth case it is shown that the \"dip\" in coincidence curve can be understood in\nterms of the free induction decay mechanism. This observation predicts the\ndestructive interference phenomenon to occur even for certain cases with\nseparable input two photon state, but it can only be explained in terms of \"the\ntwo photon (not two photons)interference \".",
