    "abstract": "The visibilities of second-order (single-photon) and fourth-order\n(two-photon) interference have been observed in a Young\u0027s double-slit\nexperiment using light generated by spontaneous parametric down-conversion and\na photon-counting intensified CCD camera. Coherence and entanglement underlie\none-and two-photon interference, respectively. As the effective source size is\nincreased, coherence is diminished while entanglement is enhanced, so that the\nvisibility of single-photon interference decreases while that of two-photon\ninterference increases. This is the first experimental demonstration of the\ncomplementarity between single- and two-photon interference (coherence and\nentanglement) in the spatial domain.",
