On single-photon quantum key distribution in the presence of loss [PDF]
, 2006 We investigate two-way and one-way single-photon quantum key distribution (QKD) protocols in the presence of loss introduced by the quantum channel. Our analysis is based on a simple precondition for secure QKD in each case. In particular, the legitimate

Measurement-device-independent quantum key distribution with leaky sources
Scientific Reports, 2021 Measurement-device-independent quantum key distribution (MDI-QKD) can remove all detection side-channels from quantum communication systems. The security proofs require, however, that certain assumptions on the sources are satisfied.
