Abstract
A physical random number generator based on the intrinsic randomness of qua ntum mechanics is described. The random events are realized by the choice o f single photons between the two outputs of a beam splitter. We present a s imple device, which minimizes the impact of the photon counters' noise, dea d-time and after pulses.
