论文摘要
我们计算Lu等人的量子密钥回收（QKR）协议的密钥共享率。密钥共享率是关键率的另一个版本，但是可以针对量子密钥分布（QKD）协议和QKR协议计算。我们定义了本研究中的关键共享率，并将QKR协议的关键共享率与QKD协议的速率进行了比较。我们发现，在某些情况下，Lu等人的QKR协议可用于比BB84更有效地共享密钥。我们还将Lu等人的QKR协议的六态版本与六态QKD协议进行了比较。这项研究的结果表明，使用预共享密钥替换量子协议中的公众讨论的潜在优势。
We calculate the key sharing rate of Lu et al.'s Quantum Key Recycling (QKR) protocol. The key sharing rate is another version of the key rate, but it can be calculated for both the Quantum Key Distribution (QKD) protocols and the QKR protocols. We define the key sharing rate in this study and compare the key sharing rate of the QKR protocol to the rate of the QKD protocols. We found Lu et al.'s QKR protocol can be used to share keys more efficiently than BB84 in some situations. We also compare the six-state version of Lu et al.'s QKR protocol to the six-state QKD protocol. The results of this study show the potential advantages of using pre-shared keys to replace the public discussion in quantum protocols.
