This paper proves finite-key BB84 security with leaky receivers, requiring only a fidelity bound on the leaked states, and gives a loss-tolerant penalty for post-measurement outcome leakage.

Phase-error estimation for quantum key distribution with leaky receivers
This paper proves finite-key BB84 security with leaky receivers, requiring only a fidelity bound on the leaked states, and gives a loss-tolerant penalty for post-measurement outcome leakage.
