量子密钥回收可以比BB84更有效地共享密钥

Quantum Key Recycling can share key more efficient than BB84

Yu-Chin Lu, Chia-Wei Tsai, Tzonelih Hwang

摘要:

我们计算了Lu等人的密钥共享率。的量子密钥回收(QKR)协议。密钥共享速率是密钥速率的另一个版本,但是它可以针对量子密钥分发(QKD)协议和QKR协议两者来计算。我们定义了密钥共享率,并将QKR协议的密钥共享率与QKD协议的密钥共享率进行了比较。我们找到了卢等人的QKR协议在某些情况下可以比BB84更有效地共享密钥。我们还比较了六个国家的版本Lu等人。的QKR协议改进为六态QKD协议。本研究的结果显示了在量子协议中使用预共享密钥来取代公开讨论的潜在优势。

英文摘要:

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.
