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…
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…
Imperfect detectors for adversarial tasks with applications to quantum key distribution
Shlok Nahar, Devashish Tupkary, Norbert Lütkenhaus
Security analyses in quantum key distribution (QKD) and other adversarial quantum tasks often assume perfect device models. However, real-world implementations often deviate from t…
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…
