Embodiment Construction

[0020] specific implementation plan

[0021] A method for generating random numbers based on chaotically amplified quantum noise, comprising the steps of:

[0022](1) Build a balanced zero-beat detection system for measuring chaotically amplified quantum noise: the single-mode continuous laser light emitted by a semiconductor laser 1 with a center wavelength of 1550 nm first passes through the first half-wave plate 2 to regulate its polarization direction; then, The single-mode continuous laser passes through the first polarizing beam splitter 3, and the laser is divided into two beams, wherein the transmitted light is P light, and the P light is a beam of linearly polarized light whose polarization direction is within the plane of the optical path. The first half-wave plate 2 and The first polarizing beam splitter 3 cooperates to control the light intensity of the P light; the transmitted light passes through the second half-wave plate 4 to change the polarization direction, ...

Abstract

The invention relates to a true random number generator, in particular to a random number generation method based on chaotic amplification quantum noise. The scheme mainly includes the following steps: Firstly, the proportion of electronic noise and quantum spontaneous emission noise in the initial steady state of chaotic laser without feedback is measured and analyzed, and the proportion of quantum noise entropy content is determined; The natural invariant probability distribution of the chaotic system is determined. Based on the distribution, the frame threshold is set to ensure that the distribution probability in each threshold interval is equally divided, the random bits are generated by binary conversion, and the true random sequences are extracted by the generalized hash function. The method of the invention realizes the effective improvement of the generation rate of the vacuum quantum random number, and provides a new method for preparing a high-entropy and high-reliability true random number generator.
