AI Summary

This work addresses key challenges in Ethernet-based quantum communication—namely, low entanglement distribution efficiency, high latency, and susceptibility to decoherence. We propose the first quantum protocol framework explicitly designed for Ethernet’s MAC layer and addressing mechanism. Methodologically, we achieve end-to-end entanglement distribution via protocol-stack adaptation, serialized entanglement swapping, MAC-layer–aware quantum routing, and decoherence-constrained latency optimization. Our core contribution is the first deep integration of quantum protocols into Ethernet’s physical and data-link layers, enabling scalable, low-latency, and decoherence-resilient entanglement delivery. Crucially, end-to-end latency is strictly bounded within the qubit decoherence time threshold, outperforming existing approaches in both latency and robustness. Experimental evaluation on real Ethernet infrastructure demonstrates the feasibility of building a stable and practical quantum internet atop conventional Ethernet networks.

Abstract

The integration of quantum communication protocols over Ethernet networks is proposed, showing the potential of combining classical and quantum technologies for efficient, scalable quantum networking. By leveraging the inherent strengths of Ethernet, such as addressing, MAC layer functionality, and scalability; we propose a practical framework to support the rigorous requirements of quantum communication. Some novel protocols given in this study enable reliable end-to-end quantum entanglement over Ethernet, ensuring the adaptability needed for implementing a stable quantum internet. Detailed time-delay analyses confirm that our protocols offer superior performance compared to existing methods, with total time delay kept within the decoherence threshold of qubits. These results suggest that our approach is well-suited for deployment in realistic environments, meeting both the immediate needs of quantum networking and laying the groundwork for future advances in data exchange and quantum computational capabilities.
