Abstract

A quantum random number generation system includes a source of light output as a plurality of coherent states such that each state has an indeterminate number of photons, a photodetector arranged to receive the light output from the light source and to generate a photocurrent dependent on the number of photons in each coherent state, and processing circuitry connected to receive the photocurrent and arranged to convert it to generate a sequence of random numbers.
