    "abstract": "We present one- and two-photon diffraction and interference experiments\ninvolving parametric down-converted photon pairs. By controlling the divergence\nof the pump beam in parametric down-conversion, the diffraction-interference\npattern produced by an object changes from a quantum (perfectly correlated)\ncase to a classical (uncorrelated) one. The observed diffraction and\ninterference patterns are accurately reproduced by Fourier-optical analysis\ntaking into account the quantum spatial correlation. We show that the relation\nbetween the spatial correlation and the object size plays a crucial role in the\nformation of both one- and two-photon diffraction-interference patterns.",
