Abstract: The fast development of Internet of Things (IoT) devices has introduced unknown security issues in the networked systems. Classical cryptography methods are restricted to sophisticated attacks and the emerging threat of quantum computing. This survey paper presents the overview of quantum key distribution (QKD) use in IoT settings, systematic review of the research trend, technological solutions, challenges, and future developments. We examine more than 150 published in-between 2018-2025 research papers, categorize the current QKD-IoT solutions, and uncover gaps in the research. We find that hybrid QKD-classical cryptography designs provide promise of realistic IoT implementation and edge-based quantum gateways emerge as an architecture of scalable implementation.
