Experimental Observation of Spatial Antibunching of Photons
W. A. T. Nogueira, Stephen Patrick Walborn, Sebastião Pádua +1 more
We report an interference experiment that shows transverse spatial antibunching of photons. Using collinear parametric down-conversion in a Young-type fourth-order interference setup, we show interference patterns that violate classical Schwarz inequality and should not exist at all in a classical description.
