Design and Development of Quantum Entanglement-Enabled Multiparty Key Distribution Protocol for Secure Communication

Quantum communication stands at the frontier of next-generation secure communication systems, leveraging the principles of quantum mechanics to address the limitations of classical cryptography. Among quantum-based techniques, Quantum Key Distribution (QKD) has emerged as a revolutionary solution enabling provably secure key exchange. While bipartite QKD protocols (such as BB84) are well-studied, there remains a significant gap in realizing multiparty quantum key distribution (MQKD) protocols essential for secure communication across complex, distributed, and scalable network infrastructures.
The proposed project, titled “Quantum Entanglement-Enabled Multiparty Key Distribution protocol for secure communication”, aims to design and develop a novel entanglement-based MQKD protocol that will address current scalability and security challenges in quantum networks. This protocol will exploit multipartite entanglement resources to establish secure keys across multiple parties simultaneously, significantly enhancing communication security in applications such as IoT, autonomous systems, smart grids, and critical infrastructure protection.
The novelty of this work lies in architecting a distributed, scalable MQKD protocol leveraging high-dimensional entanglement states, dynamic network topologies, and quantum repeaters to ensure long-distance, loss-tolerant, and robust secure communication channels. The anticipated outcome will pioneer new frontiers in quantum-secured multiparty communications, addressing both academic and industry demands and global quantum technology development.
