Application of an improved version of McDiarmid inequality in finite-key-length decoy-state quantum key distribution

In practical decoy-state quantum key distribution, the raw key length is finite. Thus, deviation of the estimated single photon yield and single photon error rate from their respective true values due to finite sample size can seriously lower the provably secure key rate R . Current method to obtain...
