A consolidated and accessible security proof for finite-size decoy-state quantum key distribution
Jerome Wiesemann, Jan Krause, Devashish Tupkary +3
In recent years, quantum key distribution (QKD) has evolved from a scientific research field to a commercially available security solution, supported by mathematically formulated s…
Dynamic rerouting and interruption resilience of quantum communication via single-photon-based resynchronization
Jan Krause, Stephanie Renneke, Jonas Hilt +5
We present a resynchronization method for quantum key distribution (QKD) systems that enables rapid and reliable recovery from interruptions of the quantum channel and changes of i…
Exponential-recovery model for free-running SPADs with capacity-induced dead-time imperfections
Jan Krause, Nino Walenta
Current count-rate models for single-photon avalanche diodes (SPADs) typically assume an instantaneous recovery of the quantum efficiency following dead-time, leading to a systemat…
Ad-hoc hybrid-heterogeneous metropolitan-range quantum key distribution network
Matthias Goy, Jan Krause, Ãmer Bayraktar +37
This paper presents the development and implementation of a versatile ad-hoc metropolitan-range Quantum Key Distribution (QKD) network. The approach presented integrates various ty…
