A rigorous and complete security proof of decoy-state BB84 quantum key distribution
Devashish Tupkary, Shlok Nahar, Amir Arqand +2
We present a rigorous and complete security proof of the decoy-state BB84 quantum key distribution (QKD) protocol. Our analysis aims to achieve a high standard of mathematical rigo…
Authentication in Security Proofs for Quantum Key Distribution
Devashish Tupkary, Shlok Nahar, Ernest Y. -Z. Tan
Quantum Key Distribution (QKD) protocols rely on authenticated classical communication. Typical QKD security proofs are carried out in an idealized setting where authentication is…
Phase error estimation for passive detection setups with imperfections and memory effects
Zhiyao Wang, Devashish Tupkary, Shlok Nahar
We develop a generic framework to bound the phase error rate for quantum key distribution protocols using passive detection setups with imperfections and memory effects. This frame…
Improved finite-size effects in QKD protocols with applications to decoy-state QKD
Lars Kamin, Devashish Tupkary, Norbert Lütkenhaus
We present a finite-size security proof for generic quantum key distribution protocols against independent and identically distributed collective attacks and extend it to coherent…
