Abstract:
A random number generating includes a light source to emit a luminous flux having light intensity distribution symmetrical about a center axis, and a plurality of single-photon detectors arranged at an equal radial distance from an extending line of the central axis of the light source to generate a bit value of either 0 or 1 according to whether a photon is detected or not.
