Abstract

A pair of orthogonally polarized signal and idler photons, generated in spontaneous parametric downconversion (SPDC), are directed to different directions for coincidence measurement by two distant photon- counting detectors. A Young’s double slit (or a single slit) is inserted into the path of the signal beam. Surprisingly, an interference (or diffraction) pattern is observed in the coincidences when the detector is scanned in the idler beam. This effect is even more striking when one considers that there is not any first-order interference- diffraction pattern behind the slits! This experiment demonstrated a typical Einstein- Podolsky-Rosen (EPR) phenomenon.1
