【摘要】：智能化变电站、换流站内复杂多变的电磁环境会使其中的量子通信系统产生量子比特差错问题。为了解决该问题,提出一种量子通信纠错编解码方法,并用量子逻辑给出相应的量子线路实现方式。通过引入8个量子比特的冗余,通过量子逻辑哈达玛(Hadamard)门和异或门及量子逻辑操作X、Z、?Z和ZX,实现了4种不同差错情况的量子比特纠错,从而保证全双工量子通信系统的正常工作。为了实现信息传输时兼顾高效性与安全性,提供一种新的技术体制和技术方案,对未来变电站、换流站的智能化发展提供了一种新的建设思路。
[Abstract]:In order to solve the problem of quantum bit error caused by complex electromagnetic environment in intelligent substation and converter station, a method of error correction and decoding for quantum communication is proposed. By introducing the redundancy of eight quantum bits, using the quantum logic Hadamard gate and Xanzhuan gate and quantum logic, we can operate XPZ? Z and ZX realize four kinds of quantum bit error correction in different error cases, so as to ensure the normal operation of full-duplex quantum communication system. In order to realize the high efficiency and security of information transmission, a new technical system and technical scheme are provided. For the future substation, the intelligent development of converter station provides a new way of construction.
