如何不丢弃QKD中的一半病例
How not to discard half of the cases in QKD
摘要：
所有已知的QKD协议都要求各方在选择了重复基时丢弃结果。在本文中，我们表明，这是没有必要的。我们给出了QKD协议的例子，这些协议与标准协议一样安全，但当碱基不同时不涉及丢弃结果，甚至不需要宣布碱基。这导致了更大的通信信道容量，并使一些窃听策略变得无用，但最重要的是，它们为我们提供了更好的洞察量子密码学基础的一般结构，并有助于建立什么是可能的，什么是不可能的边界。
英文摘要：
All known QKD protocols require the parties to discard the results when they have chosen differen bases. In this paper we show that it is not necessary. We give examples of QKD protocols that are as safe as standard ones but do not involve the discarding the results when the bases are different or even that do not require the announcement of the bases. This leads to greater communication channel capacities and render some eavesdropping strategies useless but the most important thing is that they provide us better insight into the general structures that underlie the quantum cryptography and help to establish the boundaries of what is possible and what is not.
