METHOD OF COMMUNICATION Russian patent published in 2018 - IPC H04B10/70 

FIELD: quantum physics.

SUBSTANCE: invention relates to a method of communication using quantum entanglement. Proposed method of communication consists in irradiating two spatially separated thermoluminescent crystals, containing electronically centered color centers that are mechanically entangled between them, on the transmitting and receiving sides with photons of coherent monochromatic light. After providing a difference in the photon frequency of the coherent monochromatic light between the transmitting and receiving sides, the difference in the frequency of the secondary waves emitted by quantum mechanically entangled electronic color centers from the photon frequency of coherent monochromatic light on the indicated sides is determined, while the secondary waves from the said light are extracted, and then their duration is measured, according to the transmitted binary symbols "1" or "0".

EFFECT: technical result achieved from the implementation of the claimed invention is to expand the arsenal of devices of the same purpose, namely, transmission and reception of information over a distance based on quantum correlation.
