Security proofs for practical QKD: variations, techniques, gaps, and limitations

Devashish Tupkary, Ernest Y. -Z. Tan, Shlok Nahar +2

We review the current status of security proofs for practical decoy-state Quantum Key Distribution using the BB84 protocol, focusing on optical implementations with weak coherent p…

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…

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…

Rényi security framework against coherent attacks applied to decoy-state QKD

Lars Kamin, John Burniston, Ernest Y. -Z. Tan

We develop a flexible and robust framework for finite-size security proofs of quantum key distribution (QKD) protocols under coherent attacks, applicable to both fixed- and variabl…
