Abstract

Fifty years ago, physicists Robert Hanbury Brown and Richard Twiss noticed that pho­tons from the star Sirius tended to arrive at a pair of detectors at the same time. They realized that this "bunching" effect was permissible for photons because they are bosons. Since then, the corresponding "anti-bunching" effect has been noted for fermions. Such quantum effects provide an important tool to unveil many complex and novel quantum phenomena.
