A bottleneck in the continuous-variable quantum random number generation rate is mainly as follows: low quantum entropy content in actual quantum measurement on quantum entropy source, and low real-time post-processing rate in extraction of true random numbers. Therefore, the present disclosure aims to provide a method of real-time high-speed quantum random number generation based on chaos amplifying quantum noise, to greatly increase the quantum entropy content through the chaos amplifying quantum noise, perform parallel implementation of universal Hash post-processing of multichannel quantum random numbers, and implement real-time high-speed quantum random number generation. The present disclosure provides a cost-effective, highly scalable, and highly integrated entropy-increase scheme for device-independent, semi-device-independent, and device-trusted quantum random number generators that use continuous-variable quantum noise as an entropy source, effectively promoting the application of the continuous-variable quantum random number generators.
