  We report upon a novel principle for realization of a fast nondeterministic
random number generator whose randomness relies on intrinsic randomness of the
quantum physical processes of photonic emission in semiconductors and
subsequent detection by the photoelectric effect. Timing information of
detected photons is used to generate binary random digits-bits. The bit
extraction method based on restartable clock theoretically eliminates both bias
and autocorrelation while reaching efficiency of almost 0.5 bits per random
event. A prototype has been built and statistically tested.
