METHOD AND APPARATUS FOR GENERATING RANDOM NUMBER USING LIGHT SOURCE AND SINGLE PHOTON DETECTOR

摘要

Disclosed are a method and apparatus for generating a random number using a light source and a single photon detector. According to an aspect of the present embodiment, the apparatus for generating a random number includes multiple single photon detectors which are radially spaced from a light source which emits a luminous flux with the light intensity distributed symmetrically from the central axis and the extension of the central axis, and generates a bit value of either one or zero corresponding to the result of the photon detection.
