Abstract
The invention is based on a process and system for producing random numbers by means of a quantum random number generator where the method comprises the steps of operating a laser in single mode and high modulation bandwidth by means of an electrical pulse driver, transforming the phase randomized optical pulses produced before in optical pulses with random amplitude and detecting the resulting random amplitude signals by means of a fast photodiode. The numbers thus produced are truly random.
