Abstract

Observations of unusual diffraction and interference by two-photon correlation measurements are reported. The signal and idler beams produced by spontaneous parametric down conversion are sent in different directions, and detected by two distant point-like photon counting detectors. A double-slit or a single-slit is inserted into the signal beam. Interference- diffraction patterns are observed in coincidences by scanning the detector in the idler beam.
