Fault-Tolerant Quantum Key Distribution: Enabling Overclocked Modulation
Feng-Yu Lu, Jia-Xuan Li, Ze-Hao Wang +8
Implementation security, higher generation rate, and lower cost are primary missions in the domain of quantum key distributions in recent years. However, simultaneously achieving r…
Reference-Beam Attacks against Twin-Field Quantum Key Distribution using Optical Injection Locking
Sergio Juárez, Alessandro Marcomini, Mikhail Petrov +5
Twin-Field Quantum Key Distribution (TF-QKD) has become a leading protocol to bring quantum communications to the national scale. The protocol requires the establishment of a share…
Modeling and Characterization of Arbitrary Order Pulse Correlations for Quantum Key Distribution
Ainhoa Agulleiro, Fadri Grünenfelder, Margarida Pereira +4
In quantum key distribution (QKD) implementations, memory effects caused by the limited bandwidth of modulators and/or other active devices can leak information about previous sett…
Numerical security analysis for quantum key distribution with partial state characterization
Guillermo Currás-Lorenzo, Álvaro Navarrete, Javier Núñez-Bon +2
Numerical security proofs offer a versatile approach for evaluating the secret-key generation rate of quantum key distribution (QKD) protocols. However, existing methods typically…
Quantum key distribution overcoming practical correlated intensity fluctuations
Jia-Xuan Li, Feng-Yu Lu, Ze-Hao Wang +8
Intensity correlations between neighboring pulses open a prevalent yet often overlooked security loophole in decoy-state quantum key distribution (QKD). As a solution, we present a…
