Problems solved by technology

In the traditional FM microwave communication, the signal to be transmitted is loaded onto the microwave by modulating the carrier frequency, and then the FM wave is received at the receiving end through the antenna horn, and the transmitted signal is extracted through modulation and demodulation. During the tuning process, the transmitted signal will be distorted, and the receiving antenna horn and demodulation circuit are greatly dependent on the carrier frequency

Abstract

The invention discloses a device and a method for receiving a quantum antenna frequency-modulated wave based on Rydberg atoms. The device and the method have the beneficial effects that: an electromagnetically induced transparent spectrum of the Rydberg atoms is used as a detection means to measure an AT splitting spectrum under the function of frequency modulation microwaves, so as to achieve receiving of the quantum antenna frequency-modulated wave based on atoms, in this way, a quantum communication receiver can be formed, and a modulated signal can be directly read without a huge antenna and a demodulation circuit, thereby overcoming the defect that a conventional microwave communication receiving end requires the huge antenna and adopts a demodulation mode; in addition, a probe has nointerference on an electric field, the device is simple and convenient, and microminiaturization can be achieved easily, thus the device is suitable for being widely promoted.

Description

technical field [0001] The invention relates to the field of microwave frequency modulation, in particular to a quantum antenna frequency modulation 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 FM microwave communication, the signal to be transmitted is loaded onto the microwave by modulating the carrier frequency, and then the FM wave is received at the receiving end through the antenna horn, and the transmitted signal is extracted through modulation and demodulation. During the tuning process, the transmitted signal will be distorted, and the receiving antenna horn and demodulation circuit are greatly dependent on the carrier frequency. For microwave communications of different frequencies, the receiving end needs to use differ...
