Finite Key Analysis of the Extended B92 Protocol
This work addresses the problem of finite-key effects in quantum cryptography for researchers, but it is incremental as it extends an existing protocol.
The authors derived a key rate expression for the extended B92 quantum key distribution protocol that accounts for finite resources, and analyzed it under various noise and key-length settings, comparing it to previous bounds.
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.
