Implementation Security in Quantum Key Distribution
Víctor Zapatero, Álvaro Navarrete, Marcos Curty · Advanced Quantum Technologies · 2024
Abstract The problem of implementation security in quantum key distribution (QKD) refers to the difficulty of meeting the requirements of mathematical security proofs in real‐life QKD systems. Here, a succint review is provided on this topic, focusing on discrete‐variable QKD setups. Particularly, we discuss some of their main vulnerabilities and comment on possible approaches to overcome them.
