Abstract

Abstract: We implemented experimentally a quantum random number generator, based on the registration of quasi-single-photon light by a silicon photo-multiplier, which allows one to reliably achieve the Poisson statistics of photocounts. The use of the optimal grouping of photocounts and a polynomial-length sequence of the method for extracting the random sequence 0 and 1 made it possible to achieve the output rate of a provably random sequence up to 75 Mbit s − 1 .
