摘要

We have presented a method to estimate parameters of the decoy state method based on one decoy state protocol for SARG04. This method has given lower bound of the fraction of single-photon counts (y_1), the fraction of two-photon counts (y_2), the upper bound QBER of single-photon pulses (e_1), the upper bound QBER of two-photon pulses (e_2), and the lower bound of key generation rate for both BB84 and SARG04. The numerical simulation has shown that the fiber based QKD and free space QKD systems using the proposed method for BB84 are able to achieve both a higher secret key rate and greater secure distance than that of S ARG04. Also, it is shown that bidirectional ground to satellite and inter-satellite communications are possible with our protocol.
