Embodiment Construction

[0050] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] This embodiment provides a quantum error correction coding method suitable for high-voltage overhead power lines, wherein the substation at one end is the sender, and the substation at the other end is the receiver. The system configuration is as follows figure 1 shown. The communication between the sender and the receiver is through the overhead optical cable line, and [5,1] stable subcode encoding and decoding technology is used. Aerial optical cables are special electrical optical cables, including OPGW optical cables, ADSS optical cables, OPPC photoelectric composite cables, etc. The coded qubit signal is transmitted in the overhead optical cable line here, and the final key output is obtained by screening the data obtained from the decoding line and the measurement base information provided by the classical ...

Abstract

The invention discloses a quantum error correction coding method applicable to high-voltage overhead power lines. Quantum equipment is respectively arranged in converting stations at two ends of an electric power overhead line, one end of the electric power overhead line is a sending end, the other end of the electric power overhead line is a receiving end, and the sending end and the receiving end adopt a [5, 1] stable disc quantum error correction coding technology. The quantum error correction coding method applicable to the high-voltage overhead power lines carries out system analysis in an electric system for the first time, chooses the quantum error correction of coding technology which is applicable to the environment of electric power aerial optical cables, solves the problems of signal error detecting and recovery in quantum noise caused by an electric power hyperbaric environment, and explores a scheme applicable to long-distance quantum signal encoding and decoding among the converting stations. The quantum error correction of coding method applicable to the high-voltage overhead power lines has the advantages of providing convenience for applying a quantum communication technology to the electric system.

Description

technical field [0001] The invention belongs to the field of computer and optical communication, and in particular relates to a quantum error correction coding method suitable for high-voltage overhead power lines. Background technique [0002] Different from ordinary optical cable lines, most of the optical cable lines used in power communication are overhead optical cables, mainly OPWG or ADSS optical cables. At the same time, there are unique properties in the power system. Communication lines are usually erected along power lines, and communication stations are mostly based on substations. [0003] In the communication of power substation, because the environment is different from the public network, its communication method should also be changed. In recent years, due to the development prospect of secure communication, quantum communication technology will be a very promising real secure communication method, but the biggest defect of QKD technology applied to the pow...
