Abstract: A single photons communication method and system is provided. In an example, an information loading module in a transmitting terminal of the single photons communication system may code to-be-sent target information as a corresponding target modulation frequency according to a pre-saved relationship between information and modulation frequency, and perform frequency modulation on a quantum state of communication light generated by a light source by using the target modulation frequency so that the transmitting terminal may send out modulated target communication light. After receiving the target communication light, an information decoding module in a receiving terminal of the single photons communication system may decode the target modulation frequency from a sequence of receiving photons of the target communication light through Fourier transform or other ways, and obtain target information corresponding to the target modulation frequency according to the relationship between information and modulation frequency.

Abstract: A frequency measurement method and a system thereof are provided. The method includes: generating to-be-detected emergent light under an action of the electro-optical crystal when a light source irradiates an electro-optical crystal disposed in the microwave electric field; detecting, by a single-photon detector, the to-be-detected emergent light to obtain a detection result of the single-photon detector; and determining a frequency of the microwave signal based on the detection result of the single-photon detector and a Fourier transform algorithm.
