空间平台量子密钥纠错处理研究

空地量子通信受诸多因素的影响，量子密钥的原始码存在一定的误码率，需要通过空间平台与和地面之间的双向数据交互对错误的密钥进行纠正。受空间平台硬件设备限制，数据的传输速度、存储空间以及处理能力等均有限，对空间平台量子纠错算法提出了更高的要求。为此给出了一种适合空间平台环境的基于汉明码的Winnow纠错算法，这种纠错处理算法不仅容易实现，而且在空间平台资源受限的情况下可以兼顾运算效率和纠错效率。

Research on Quantum Key Error Correction in Space Platform

In the space-ground quantum communication, affected by many factors, the original code quantum key has a certain bit error rate, so the classical communication between space platform and ground requires the correction of the error bits. Due to the limitations of the hardware equipment, transmission speed, data storage and processing capacity on the space platform, higher requirements are imposed on the quantum error correcting algorithm. In this paper, the Winnow error correction algorithm suitable for space-platform environment was proposed based on the Hamming code. This error correction processing algorithm program is easy to implement, and in the case of space platforms with limited resources, it can consider both the operational efficiency and the error correction efficiency.
