We present a set of random number generator based on a quantum mechanical source, which is the process of splitting a beam of photons on a polarizing beam splitter. The randomness of the polarizing photon is detected by the synchronous single-photon coincidence detection technique. The random bit data are transferred to a personal computer via a digital I/O interface. The random numbers are tested by the Pseudo-random Number Sequence Test Program(ENT) which is the most popular random number test program in the world. The result is perfect.
