Quantum generation of random numbers makes it possible to obtain truly random numbers that can be used in applications where a high degree of randomness is needed. This paper presents an estimate of how the nonideal nature of the setup parameters affects the results of measurements carried out for two quantum random-number generators: one based on separation of laser radiation, and one based on the use of vacuum fluctuations.
