Enforcing IID structure on time-bin encoded QKD protocols via coarse-graining
Shlok Nahar, Shihong Pan, Norbert Lütkenhaus
The paper shows that by discarding detector outcomes that depend on inter‑round coherence, Bob’s measurement in time‑bin QKD can be turned into an IID product‑POVM, allowing standa…
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…
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,…
Quantum Chernoff divergence in advantage distillation for quantum key distribution and device-independent quantum key distribution
Mikka Stasiuk, Norbert Lütkenhaus, Ernest Y. -Z. Tan
Device-independent quantum key distribution (DIQKD) aims to mitigate adversarial exploitation of imperfections in quantum devices, by providing an approach for secret key distillat…
