Estimation of decoy state parameters for practical QKD

We have presented a method to estimate parameters of the decoy state method based on one decoy state protocol for both BB84 and SARG04. This method has given different lower bound of the fraction of single-photon counts (y1), the fraction of two-photon counts (y2), the upper bound QBER of single-pho...
