Future-Proofing Quantum Networks: Blockchain's Role in Secure Key Distribution and Authentication

Quantum networks promise unparalleled security benefits, leveraging the principles of quantum mechanics for secure communication. However, practical challenges, such as key distribution and authentication, remain pivotal concerns. Blockchain technology, with its decentralized and immutable nature, provides a compelling solution for enhancing the security of quantum networks. This review paper explores the integration of blockchain with quantum networks, highlighting its role in secure key distribution and authentication mechanisms. We examine existing models, challenges, and future directions in the field, offering insights into how blockchain can fortify quantum communication networks against emerging threats.
