Abstract

The invention provides a quantum random number generation device, method and equipment based on a coherent light receiver. The quantum random number generation device comprises a local oscillator light source, the coherent light receiver and a data acquisition and processing module, wherein the local oscillator light source is connected to one input end of the coherent light receiver, and the other input end of the coherent light receiver has no light input and is used as a vacuum state input end; the coherent optical receiver is configured to perform beam splitting, polarization, interference and conversion on input light to obtain a voltage signal; the output end of the coherent optical receiver is connected with a data acquisition and processing module, and the data acquisition and processing module is configured to perform data acquisition on the voltage signal output by the coherent optical receiver and quantify the voltage signal to generate analysis data, and then process the analysis data through a random number post-processing method to generate a random number. The device, the method and the equipment have the advantages of high stability, miniaturization and low cost, and multi-channel random number generation can be realized.

Description

Technical field [0001] The present disclosure belongs to the technical field of quantum random number, and more particularly to a quantum random number generating apparatus, method, and apparatus based on a coherent light receiver. Background technique [0002] The statement of this section is merely the background technology information related to the present disclosure, which is not necessarily constituted in prior art. [0003] The random number is a widely used basic resource, while the random number generator is a device used to generate a random number sequence. Good performance random number generators in many areas such as quantum communication, cryptography, gaming industry, Monte Carlo simulation, numerical calculations, random sampling, etc. have wide application. In the existing quantum random number generator scheme, a single photon path selection is selected, its bit rate can reach 1 Mbps order; and the bit rate reaches the bit rate of 100 Mbps. For next-generation ...
