Measurement-device-independent Quantum Key Distribution with Pulse-position Modulation

Efficient quantum private queries based on quantum key distribution with pulse-position modulation

“…In 2015, Zhong et al [16] designed and demonstrated a new PPM-QKD protocol with decoy-state. In 2017, Mao et al [17] designed an efficient measurement-device-independent (MDI)-QKD protocol using polarization coding based on PPM modulation. In 2018, Wang et al [19] have presented a novel passive PPM-MDI-QKD protocol with the two-mode source.…”

“…In 2018, Wang et al [19] have presented a novel passive PPM-MDI-QKD protocol with the two-mode source. Compared with PPM-QKD protocols [12,[14][15][16][17], the PPM-MDI-QKD protocol is completely free of eavesdropping from the measurement device and has an extended communication range [18]. However, the MDI-QKD protocols [19] that are based on the polarization encoding or phase encoding schemes are affected by the basis dependence problem.…”
