Quantum entanglement, a fundamental phenomenon of quantum mechanics where particles become interconnected such that the state of one instantaneously influences the other regardless of distance, has emerged as a critical resource for next-generation communication systems. This study explores the role of quantum entanglement in advancing secure and efficient communication technologies, particularly focusing on quantum key distribution (QKD), quantum teleportation, and entanglement-based quantum networks.
The paper reviews recent developments in generating, maintaining, and utilizing entangled states for robust communication, highlighting how entanglement enables fundamentally secure information exchange by leveraging quantum non-locality and the no-cloning theorem. Various physical implementations, including photonic systems and trapped ions, are analyzed for their effectiveness in real-world communication scenarios.
Through theoretical modeling and simulation, we evaluate the performance benefits of entanglement-based protocols over classical counterparts, particularly in enhancing security against eavesdropping and improving communication latency and capacity. The challenges of entanglement distribution over long distances, decoherence, and scalability are addressed by reviewing quantum repeater architectures and error correction techniques.
Results demonstrate that quantum entanglement can significantly enhance communication security and pave the way for quantum internet infrastructure, although practical deployment demands overcoming hardware and environmental limitations. The research underscores the transformative potential of quantum entanglement in revolutionizing communication systems, enabling ultra-secure, high-speed, and low-latency data transmission.
Future work will focus on experimental validation of scalable entanglement distribution methods, hybrid quantumclassical network integration, and optimization of quantum protocols to realize practical next-generation communication networks.
