Abstract
The present disclosure provides a method and device for performing signal communication based on a levitated particle. In one example, the method includes: preparing a levitated state of the particle; regulating and measuring a net charge quantity carried by the levitated particle; calibrating electromagnetic response characteristics of the levitated particle; applying an electromagnetic communication signal; obtaining and demodulating the electromagnetic communication signal. In an example, the device includes: a levitation trapper; a charge measure-regulator; an electromagnetic response calibrator, configured to obtain, in advance, a background noise and an electromagnetic response transfer function of the levitated particle; a communication signal detect-demodulator, configured to detect a motion response of the levitated particle under an electromagnetic communication signal; based on the background noise and the electromagnetic response transfer function of the levitated particle, recover the applied electromagnetic communication signal from the detected motion response, and demodulate symbols of the electromagnetic communication signal.
