Phase error rate estimation in QKD with imperfect detectors
Devashish Tupkary, Shlok Nahar, Pulkit Sinha +1
We present a finite-size security proof of the decoy-state BB84 QKD protocol against coherent attacks, using entropic uncertainty relations, for imperfect detectors. We apply this…
Improved Decoy-state and Flag-state Squashing Methods
Lars Kamin, Norbert Lütkenhaus
In this work, we present an improved analysis for decoy-state methods, enhancing both achievable key rates and recovering analytical results for the single intensity scenario. Our…
Finite-size analysis of prepare-and-measure and decoy-state QKD via entropy accumulation
Lars Kamin, Amir Arqand, Ian George +2
An important goal in quantum key distribution (QKD) is the task of providing a finite-size security proof without the assumption of collective attacks. For prepare-and-measure QKD,…
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…
