Abstract

In recent years, quantum network technology has been rapidly developing, with new theories, solutions, and protocols constantly emerging. The breakthrough experiments and achievements are impressive, such as the construction and operation of ultra-long-distance and multi-user quantum key distribution (QKD) networks, the proposal, verification, and experimental demonstration of new network nonlocality characteristics, etc. The results of recent research on QKD and network nonlocality are summarized and analyzed in this paper, including CV-MDI-QKD (continuous-variable measurement-device-independent QKD), TF-QKD (twin-field QKD), AMDI-QKD (asynchronous MDI-QKD), the generalization, sharing, and certification of network nonlocality, as well as the main achievements and related research tools of full network nonlocality and genuine network nonlocality, aiming to identify the current status and future development paths of the QKD and network nonlocality.

摘要

近年来，量子网络技术发展迅速，新理论、解决方案和协议不断涌现。突破性的实验和成果令人印象深刻，例如超长距离和多用户量子密钥分发（QKD）网络的构建与运行、新网络非定域性特征的提出、验证及实验演示等。本文对QKD和网络非定域性的近期研究成果进行了总结与分析，包括连续变量测量设备无关QKD（CV-MDI-QKD）、双场QKD（TF-QKD）、异步测量设备无关QKD（AMDI-QKD）、网络非定域性的推广、共享和认证，以及全网络非定域性和真正网络非定域性的主要成果及相关研究工具，旨在明确QKD和网络非定域性的现状及未来发展路径。
