论文摘要
和解是一种机制，可以淘汰两个相关变量之间的差异。它在每个量子密钥分布方案中都具有重要的作用，在这种方案中，必须通过嘈杂的通道或在存在窃听的情况下进行研究。在本文中，我们表明，对于离散可变的QKD协议，可以通过Turbo代码来有利地解决此问题。特别是，我们证明我们的方法会导致位错误率的显着提高，即使具有出色的窃听功能，也可能在存在窃听器的情况下将其除以三。
Reconciliation is a mechanism allowing to weed out the discrepancies between two correlated variables. It has great role in every Quantum Key Distribution protocol where the key has to be transmitted through a noisy channel or as in our case of study in presence of an eavesdropping. In this paper, we show that for discrete-variable QKD protocols, this problem can be advantageously solved with Turbo codes. In particular, we demonstrate that our method leads to a significant improvement of Bit Error Rate, may divide it by three in presence of a eavesdropper even with great eavesdropping capability.
