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…
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…
Postselection technique for optical Quantum Key Distribution with improved de Finetti reductions
Shlok Nahar, Devashish Tupkary, Yuming Zhao +2
The postselection technique is an important proof technique for proving the security of quantum key distribution protocols against coherent attacks. In this work, we go through mul…
