Abstract

The invention discloses a Rydberg-atom-based quantum antenna amplitude modulation wave receiving device and method. An electromagnetic induction transparent spectrum with the Rydberg atom is used as adetection way and an AT split spectrum under the effect of an amplitude modulation microwave is measured, so that atom-based amplitude-modulated microwave quantum antenna and communication receiver are realized and a modulation signal is read out directly; and the traditional modulation and demodulation are realized and a defect that the traditional microwave communication receiving terminal needs a demodulation mode is overcome. The quantum antenna causes no interference on the electric field. The receiving device that is simple and is easy to realize miniaturization is suitable for wide application.

Description

technical field [0001] The invention relates to the field of AM wave receiving antennas, in particular to a quantum antenna AM wave receiving device and method based on Rydberg atoms. Background technique [0002] Microwave communication has become one of the main means of communication at present, and it has great significance in the fields of social life, scientific research and military affairs. In the traditional AM microwave communication, the signal to be transmitted is loaded onto the microwave by modulating the amplitude of the carrier wave, and then the AM signal is received through the antenna at the receiving end, and the transmitted signal is extracted through the demodulation circuit, but the carrier wave of the AM wave The frequency is tens to hundreds of kHz, the receiving antenna is huge, and different frequencies require different receiving antennas. The demodulation process also results in distortion of the transmitted signal. Contents of the invention ...
