description The invention discloses a quantum random number generator entropy quality monitoring method and device in the technical field of information security, and aims to solve the problem of low efficiency of the existing technical scheme. Comprising the following steps: preparing a quantum state corresponding to an entropy source, and measuring the quantum state to obtain quantitative analysis data; the total data amount of the quantitative analysis data is calculated according to the specified window size W, and the total data amount A is obtained; the entropy rate of the quantitative analysis data is calculated in real time and serves as an entropy estimation value H; calculating a critical value C according to a specified window size W, a false positive probability alpha and the received entropy estimation value H; and judging whether the data total amount A and the critical value C pass quality monitoring or not. According to the method, the high-performance quantization characteristic of the quantum random num
