Quantum images in double-slit experiments with spontaneous down-conversion light

Abstract

A fourth-order correlation function in the {r} space is developed and applied to double-slit experiments with spontaneous down-conversion light. The predicted coincidence patterns and corresponding degrees of visibility agree with the experimental results. The van Cittert--Zernike theorem is extended to coincidence experiments. \textcopyright{} 1996 The American Physical Society.
