Improving Parameter Optimization in Decoy-State Quantum Key Distribution

Figure 5

Comparison of optimized key rate using an LSA versus GA: (a) BB84 QKD protocol, (b) asymmetric MDI-QKD protocol, (c) symmetric MDI-QKD protocol, and (d) RFI-MDI-QKD protocol. In each subfigure, the blue and red dotted lines denote the expected key rates using LSA and GA, respectively.
