Motorized remote quantum communication method based on self-destructible trusted relay

Abstract

The invention discloses a motorized remote quantum communication method based on a self-destructible trusted relay, which replaces channel loss cost with time delay cost, and realizes improvement of an equivalent communication distance: safety-critical information is transmitted to a motorized relay through a point-to-point quantum communication system, the motorized relay has a higher moving speed, the motion control system and the information exchange system do not influence each other from the physical level, self-destruction of the information exchange system is started when the maneuvering relay is interfered by the outside, and the maneuvering relay carrying safety-critical information moves to a receiver at a high speed and transmits the safety-critical information to the receiver through the point-to-point quantum communication system. At the moment, the sender and the receiver with the long spatial distance finish one-time forwarding one-way communication with time delay. According to the invention, a brand new solution is provided for one-way communication application which can tolerate hourly-order transmission delay but strongly requires secret keys and information not to fall to the ground, the problem of channel loss which cannot be solved by long-distance quantum communication is solved, and the method can be used as a brand new quantum communication working mode, supports the construction of a wide-area coverage quantum communication network, and provides a solution for network space security defense.

Description

technical field [0001] The present invention belongs to the subject of quantum communication, and specifically refers to a high-speed mobile platform as a relay, which has a certain time delay tolerance, and realizes ultra-long-distance non-real-time quantum communication through the high-speed maneuvering of the information relay platform to compensate for the loss of free space optical channels The method, especially relates to a method, system and storage medium of mobile remote quantum communication based on a self-destructible trusted relay. Background technique [0002] Quantum communication is a cutting-edge communication technology that realizes information security interaction through the simultaneous sharing of quantum states of remote users. Based on the Heisenberg uncertainty principle, quantum inseparability principle, quantum non-cloning principle, etc., quantum communication has theoretical endogenous security, that is, eavesdroppers cannot eavesdrop on the co...

Problems solved by technology

[0003] Whether it is quantum key distribution or quantum direct communication, it will face the limitation of communication channel loss. Limited by the endogenous properties of quantum communication signals that cannot be copied, it is difficult for classical communication relay methods to support the doubling of quantum communication distances.

Although trusted relay can improve the transmission distance of quantum communication, it brings hidden dangers to communication security (keys and information have a landing process), and the quantum relay technology without keys and information is not mature enough to support long-distance quantum communication.
