Detectability Limits for Intra-Block Temporal Drift in Finite-Key Entanglement-Based QKD
Rafael Duarte Marcelino, Julio Smanioto Garcia, Matheus Rufino
We study the statistical detectability of intra-block temporal drift in finite-key entanglement-based quantum key distribution, with particular relevance to E91-type parameter esti…

A Formal Basis for Quantum Cryptographic Exposure Measurement under HNDL Threat
Matheus Rufino, Rafael Duarte Marcelino, Julio Smanioto Garcia
An adversary copies your encrypted traffic today and waits for a quantum computer to decrypt it later. How exposed are you? We show that the functional form of the answer is not me…
