Embodiment Construction

[0020] A method for high-speed generation of quantum random numbers based on vacuum state quantum fluctuations, comprising the following steps:

[0021](1) Build a balanced zero-beat detection system for measuring the quantum state of the light field: the single-mode continuous laser light emitted by the semiconductor laser 1 with a center wavelength of 1550nm first passes through the optical isolator 2 to ensure that the laser light will not return to the laser and affect its stable operation; then The first optical beam splitter 3 divides the laser light into two beams, wherein the transmitted laser light provides the background light of the whole zero-beat detection system, and the half-wave plate 4 and the second optical beam splitter 5 cooperate to control the light intensity of the background light; The laser light reflected by the first optical beam splitter 3 is used as the translational light of the vacuum field translational action, and an electro-optic modulator 6 wi...

Abstract

The invention relates to a high-speed true random quantum number generating method, in particular to a method for producing random quantum number at high speed based on vacuum state quantum fluctuation. The problem that the production speed of an existing vacuum random quantum number generator is lower is solved. According to the specific scheme, the high-speed true random quantum number generating method mainly comprises the following steps that the translation effect of Gaussian distribution is firstly exerted to a vacuum state in a phase space, amplification of vacuum-state orthogonal amplitude component noise in the phase space is achieved, and the entropy content introduced by quantum noise in a system is increased; the true random bits which can be extracted in data postprocessing are increased; the background light of a homodyne detection system is strengthened, the sensitivity of the detection system to vacuum noise is improved, and a vacuum noise measurement value is amplified, so that the framing amount of vacuum noise statistics, namely sampling quantization bits are remarkably increased. By adopting the method, the vacuum random quantum number generating rate is effectively improved, and a new means is provided for manufacturing of high-speed random quantum number generators.
