• Abstract: The current maturity of the quantum-secured optical data channels based on the Quantum Key Distribution (QKD) technology is at the deployment level in metro environments, while R&D efforts are also being conducted towards long-distance deployments. A great deal of research has been conducted on the achievable Secure Key Rate (SKR) for quantum channels. However, one of the major questions for network operators is the required SKR for the deployment of quantum-secured channels. This article addresses this question by defining the required SKR for quantum-secured optical channels and provides guidelines towards optimizing this parameter. \copyright 2023 The Author(s)
