Enforcing IID structure on time-bin encoded QKD protocols via coarse-graining
Shlok Nahar, Shihong Pan, Norbert Lütkenhaus
Many security proofs for quantum key distribution (QKD) require Bob's measurement to have a tensor-product structure across protocol rounds, with some techniques requiring the stro…
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…
Incorporating device characterization into security proofs
Ernest Y. -Z. Tan, Shlok Nahar
Typical security proofs for quantum key distribution (QKD) rely on having some model for the devices, with the security guarantees implicitly relying on the values of various param…
Security of quantum key distribution with source and detector imperfections through phase-error estimation
Guillermo Currás-Lorenzo, Margarida Pereira, Shlok Nahar +1
Quantum key distribution promises information-theoretic security, but practical implementations face vulnerabilities due to device imperfections. Existing security proofs typically…
