Phase Noise in Real‐World Twin‐Field Quantum Key Distribution
Phase Noise in Real‐World Twin‐Field Quantum Key Distribution
Abstract The impact of noise sources in real‐world implementations of twin‐field quantum key distribution (TF‐QKD) protocols is investigated, focusing on phase noise from photon sources and connecting fibers. This work emphasizes the role of laser quality, network topology, fiber length, arm balance, and detector performance in determining key rates. Remarkably, …
