Measurement-device-independent quantum key distribution protocol with phase post-selection
Fig. 1. Comparison of the key rates with this work and the former methods under the symmetric channel. The line of Ref. [38] is the key rates of the double-scanning four-intensity MDI-QKD protocol, and the line of Ref. [29] is the key rates of the original four-intensity MDI-QKD protocol. The experiment parameters are listed in Table
Fig. 2. Comparison of the key rates with this work and the former methods under the symmetric channels. The experiment parameters here are similar to those in Fig.
Fig. 3. Comparison of the key rates with this work and the former methods under the asymmetric channels. The experiment parameters are listed in Table
Fig. 4. Comparison of the key rates with this work and the former methods under the asymmetric channels. The experiment parameters here are similar to those in Fig.
Fig. 5. Bell measurement setup of Charlie [21]. Here we take the polarization-encoding as an example to show the simulation method and the results of the phase-encoding are the same. BS, 50:50 beam splitter; PBS, polarization beam splitter;
