    "abstract": "The theoretical framework behind a recent experiment by Nogueira et. al.\n[Phys. Rev. Lett. 86}, 4009 (2001)] of spatial antibunching in a two-photon\nstate generated by collinear type II parametric down-conversion and a\nbirefringent double-slit is presented. The fourth-order quantum correlation\nfunction is evaluated and shown to violate the classical Schwarz-type\ninequality, ensuring that the field does not have a classical analog. We expect\nthese results to be useful in the rapidly growing fields of quantum imaging and\nquantum information.",
