In this paper we derive a key rate expression for the extended version of the B92 quantum key distribution protocol that takes into account, for the first time, the effects of operating with finite resources. With this expression, we conduct an analysis of the protocol in a variety of different noise and key-length settings, and compare to previous bounds on comparable protocols.

扩展B92协议的有限密钥分析

在本文中，我们推导出了 B92 量子密钥分发协议的扩展版本的密钥速率表达式，该表达式首次考虑了有限资源操作的影响。使用这个表达式，我们在各种不同的噪声和密钥长度设置下对协议进行分析，并与之前类似协议的界限进行比较。
