While quantum communication promises unbreakable security, real-world deployments are vulnerable to physical, protocol, and operational risks. Our work presents a structured framework for analysing these threats, combining a TTP-style (Tactic, Technique, Procedure) approach with a specific risk assessment methodology. We introduce SQOUT, a quantum threat intelligence platform, and illustrate its application using a Photon-Number-Splitting (PNS) attack kill chain. Furthermore, we apply established international standards and best practices for information security risk management to assess quantum-specific risk scenarios, providing practical guidance for safeguarding emerging quantum infrastructures.","short_abstract":"This paper addresses the urgent need for a cybersecurity framework tailored to quantum communication systems as the world transitions to quantum-safe infrastructures.
