Rigorous phase-error-estimation security framework for QKD with correlated sources

Practical QKD modulators introduce correlations between consecutively emitted pulses due to bandwidth limitations, violating key assumptions underlying many security proof techniques. Here, we address this problem by introducing a simple yet powerful mathematical framework to directly extend phase-error-estimation-base...

Phase-error estimation for quantum key distribution with leaky receivers

A simple finite-key security proof based on phase-error estimation for prepare-and-measure QKD in the presence of either a priori information leakage about the basis choices and/or a posteriori information leakage about the measurement outcomes is presented.

Deterministic QKD source robust against side-channel attacks

This work proposes a QKD source that is intrinsically robust against side-channel attacks, and under idealized source assumptions commonly adopted in proposals for existing schemes, conventional decoy-state security analyses apply directly, yielding substantially higher key rates.
