    "abstract": "We study first-order interference in spontaneous parametric down-conversion\ngenerated by two pump pulses that do not overlap in time. The observed\nmodulation in the angular distribution of the signal detector counting rate can\nonly be explained in terms of a quantum mechanical description based on\nbiphoton states. The condition for observing interference in the signal channel\nis shown to depend on the parameters of the idler radiation.",
