论文摘要
本文研究了一种新的信息核对方法，用于量子密钥分布的情况下，在有恶毒的窃听者存在下两个方面的钥匙。我们已经观察到，对帐是渠道编码的特殊情况，对于现有技术，可以调整和解。我们描述了一种基于涡轮代码的明确对帐方法。我们认为，提出的方法可以根据离散量子状态提高量子密钥分布协议的效率。
This paper investigates a new information reconciliation method for quantum key distribution in the case where two parties exchange key in the presence of a malevolent eavesdropper. We have observed that reconciliation is a special case of channel coding and for that existing techniques can be adapted for reconciliation. We describe an explicit reconciliation method based on Turbo codes. We believe that the proposed method can improve the efficiency of quantum key distribution protocols based on discrete quantum states.
