7. A device for performing signal communication based on a levitated particle, the device comprising:
a levitation trapper configured to levitate a particle in a non-contact manner in an environment;
a charge measure-regulator configured to generate free charges around the levitated particle, and regulate and measure a net charge quantity carried by the levitated particle;
an electromagnetic response calibrator, configured to measure a background noise and measure an electromagnetic response transfer function of the levitated particle by applying an electromagnetic communication signal to the levitated particle; and
a communication signal detect-demodulator, configured to detect a motion response of the levitated particle under the electromagnetic communication signal, and based on the background noise and the electromagnetic response transfer function of the levitated particle, recover the electromagnetic communication signal from the detected motion response, and demodulate symbols of the electromagnetic communication signal.
