摘要

量子密钥分发(QKD)可以为合法通信双方提供理论上信息安全的密钥，而信息协调作为量子密钥分发系统不可或缺的组成部分，可以基于纠错码来纠正原始密钥中存在的错误。本文首先介绍了信息对账的基本知识及其对连续变量QKD的影响。然后介绍了采用的信息方案和相应的纠错码。其次，介绍了码率兼容、调和算法的硬件加速、信息调和的研究进展及其在连续变量QKD中的应用。最后，我们讨论了未来的挑战并进行了总结。

Information reconciliation of continuous-variables quantum key distribution: principles, implementations and applications

Quantum key distribution (QKD) can provide information-theoretically secure keys for two parties of legitimate communication, and information reconciliation, as an indispensable component of QKD systems, can correct errors present in raw keys based on error-correcting codes. In this paper, we first describe the basic knowledge of information reconciliation and its impact on continuous variable QKD. Then we introduce the information schemes and the corresponding error correction codes employed. Next, we introduce the rate-compatible codes, the hardware acceleration of the reconciliation algorithm, the research progress of information reconciliation, and its application in continuous variable QKD. Finally, we discuss the future challenges and conclude.
