Abstract
Quantum communication marks a significant advancement in secure information transfer. By harnessing the principles of quantum mechanics, it provides unprecedented levels of data protection, most notably through quantum key distribution (QKD). This article explores the core concepts of quantum communication, reviews key technological developments, and examines its diverse applications in sectors such as defense, finance, and healthcare. It also addresses the major challenges that limit large-scale adoption. The discussion concludes by emphasizing the transformative potential of quantum networks, particularly when integrated with emerging technologies such as artificial intelligence (AI) and the Internet of Things (IoT).
Keywords:Quantum communication, quantum load distribution, secure information transfer, cyber security, quantum network
