Quantum Internet: Technologies, Protocols, and Research Challenges

2025-01-30

AI Summary

The quantum internet lacks a systematic introductory framework to distinguish it fundamentally from quantum computing and bridge conceptual gaps among theory, protocols, and engineering practice. To address this, we propose the first comprehensive, full-stack knowledge framework structured around six core dimensions—Why, What, How, When, Who, and Challenges. Our approach integrates quantum networking fundamentals—including quantum repeaters, entanglement distribution, and trusted nodes—with protocol stack design and a phased feasibility roadmap. We further introduce a standardization-oriented guide that unifies quantum communication principles with network engineering practices, spanning foundational concepts to open research challenges. This framework lowers entry barriers for researchers and engineers, enables rapid prototyping, supports international standardization efforts (e.g., ITU-T, IETF), and provides a reusable methodological foundation for quantum network research and development.

Abstract

As the field of the quantum internet advances, the necessity for a comprehensive guide to navigate its complexities has become increasingly crucial. Quantum computing, a more established relative, shares foundational principles with the quantum internet; however, distinguishing between the two is essential for further development and deeper understanding. This work systematically introduces the quantum internet by addressing fundamental questions: Why is it important? What are its core components? How does it function? When will it be viable? Who are the key players? What are the challenges and future directions? Through elucidating these aspects along with a comprehensive introduction to the basic concepts, we aim to provide a clear and accessible overview of the quantum internet, facilitating the groundwork for future innovations and research in the field.
