Exploring Quantum Entanglement in Multi-Particle Systems for Secure Communication

Abstract

Quantum entanglement represents one of the most profound phenomena in quantum mechanics, providing the foundation for next-generation secure communication technologies. As the field of quantum communication continues to evolve, entanglement involving multi-particle systems emerges as a crucial area for study due to its potential to enhance robustness, efficiency, and security in quantum networks. This paper explores the theoretical underpinnings, experimental advancements, and practical applications of multi-particle quantum entanglement in the context of secure communication. A detailed literature review identifies gaps and challenges in current approaches. We present a methodology based on GHZ and cluster states to evaluate their suitability for quantum key distribution (QKD) and multiparty communication protocols. Our results demonstrate improved noise resilience and higher fidelity in entanglement-based communication, highlighting the effectiveness of multi-particle configurations. The paper concludes by outlining the potential for future research in expanding entanglement to scalable quantum networks and integrating quantum repeaters to extend communication distance. This research contributes to the growing body of knowledge supporting the development of secure, efficient, and scalable quantum communication infrastructures
