Polarization-Basis Tracking Scheme in Satellite Quantum Key Distribution
Figure 15
Final key rates achieved with BB84 and for the decoy state with photons/pulse for free-space and fiber-based transmission systems at the clock rate of 2.5 GHz as a function of transmission distance. Pd stands for dark count rate in counts/pulse. The rest of parameters corresponding to the prototype model in Table 1 are assumed.
