The secret key rate of 3d-measurement-device-independent QKD (MDI-QKD) (red dashed line) and 3d-QKD with hybrid encoding (black solid line). Plot of the secret key rate R (bits/total pulse) vs. transmission loss (dB). The secret key rate per total signal is obtained from (the secret key rate per sifted key) × (the signal sifting rate). Details are described in maintext. Dark count rate of single photon detectors is assumed as per pulse.
