Quantum information has emerged as a frontier in scientific research and is transitioning to real-world technologies and applications. In this work, we explore the integration of quantum secure direct communication (QSDC) with time-sensitive networking (TSN) for the first time, proposing a novel framework to address the security and latency challenges of Ethernet-based networks. Because our QSDC-TSN protocol inherits all the advantages from QSDC, it will enhance the security of the classical communications both in the traditional TSN- and QKD-based TSN by the quantum principle and reduce the communication latency by transmitting information directly via quantum channels without using keys. By analyzing the integration of QSDC and TSN in terms of time synchronization, flow control, security mechanisms, and network management, we show how QSDC enhances the real-time performance and security of TSN. These advantages enable our QSDC-TSN to keep the balance between and meet the requirements of both high security and real-time performance in industrial control, in a digital twin of green power and green hydrogen systems in distributed energy networks, etc., showing its potential applications in future quantum-classical-hybrid systems.
量子信息已成为科学研究的前沿领域，并正在向现实世界的技术和应用转变。在这项工作中，我们首次探索了量子安全直接通信（QSDC）与时间敏感网络（TSN）的集成，提出了一个新颖的框架来应对基于以太网的网络的安全性和延迟挑战。由于我们的QSDC-TSN协议继承了QSDC的所有优点，它将通过量子原理提高传统基于TSN和基于量子密钥分发（QKD）的TSN中经典通信的安全性，并通过直接通过量子信道传输信息而不使用密钥来减少通信延迟。通过从时间同步、流量控制、安全机制和网络管理等方面分析QSDC和TSN的集成，我们展示了QSDC如何提高TSN的实时性能和安全性。这些优势使我们的QSDC-TSN能够在工业控制、分布式能源网络中的绿色电力和绿色氢系统的数字孪生等方面在高安全性和实时性能之间保持平衡并满足两者的要求，展示了其在未来量子-经典混合系统中的潜在应用。
