    摘要: The present disclosure relates to a test paper counting technology, in particular to a portable test paper counting device and method based on a single photon detector. A portable test paper counting device based on a single photon detector is provided, which includes a box-shaped housing, two guide rail pairs, two hanger rods, a laser, a reflecting mirror, a single photon detector, a power supply, and a PC computer. A rectangular operating hole penetrating from left to right is formed in a lower edge of a right side wall of the box-shaped housing. A right part of a bottom wall of the box-shaped housing is provided with an assembly hole penetrating from up to down. A left side wall of the box-shaped housing is provided with a threading hole penetrating from left to right. Sliders of the two guide rail pairs both face downwards.

    摘要: 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.
