Rigorous phase-error-estimation security framework for QKD with correlated sources
Guillermo Currás-Lorenzo, Margarida Pereira, Kiyoshi Tamaki +1
Practical QKD modulators introduce correlations between consecutively emitted pulses due to bandwidth limitations, violating key assumptions underlying many security proof techniqu…

Loss-tolerant quantum key distribution with detection efficiency mismatch
Alessandro Marcomini, Akihiro Mizutani, Fadri Grünenfelder +2
Current implementations of quantum key distribution (QKD) typically rely on prepare-and-measure (P&M) schemes. Unfortunately, these implementations are not completely secure, unles…

Characterising higher-order phase correlations in gain-switched laser sources with application to quantum key distribution
Alessandro Marcomini, Guillermo Currás-Lorenzo, Davide Rusca +3
Multi-photon emissions in laser sources represent a serious threat for the security of quantum key distribution (QKD). While the decoy-state technique allows to solve this problem,…
