- Abstract: 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.
