This paper introduces the experiment of generating binary true random sequence based on single-photon quantum randomness and the mathematical processing method adopted.Using single-photon detector, high-speed signal processing circuit and computer data acquisition system, the experiment records the random selection of reflection or refraction The path is passed through the photons of the 50/50 beamsplitter to obtain the original binary random sequence.Huffman coding is used to compress the original data into true random sequences that meet the cryptographic requirements.The rate of random sequence acquisition can theoretically reach 2 0 0 kbit / s.
