摘　　要：量子互联网是将量子节点经过量子信道连接而成的量子信息系统,其关键技术是在不同节点间使用量子隐形传态方案实现量子信息的高性能传递。目前量子信息传递的保真度、距离和容量是制约量子互联网迈向实际应用的因素,发展量子纠缠互联与中继是提升量子信息传递性能的必由之路。“银杏一号”城域量子互联系统围绕光纤通信波段量子纠缠互联与中继开展研究,具体包括高性能量子光源和量子存储器的研制、高速城域量子隐形传态和光—原子纠缠界面的实验验证。“银杏一号”的研究工作为光纤通信波段量子互联网的实用化发展奠定了重要基础。Quantum internet,consisting of quantum nodes connected by quantum channels,is a quantum information system,the key task of which is the high-performance transmission of quantum information between different nodes using quantum teleportation schemes.Currently,the fidelity,distance,and capacity of quantum information transfer remain challenges that hinder the practical application of the quantum internet.Developing quantum entanglement and quantum repeaters offers a promising solution for the above challenges.The“No.1 Ginkgo”metropolitan quantum interconnection system focuses on the process of quantum entanglement and quantum repeaters at telecom band,such as the development of high-performance quantum light sources and quantum storage devices,and the experimental verification of highspeed metropolitan quantum teleportation and lightatom entanglement interfaces.The research progress of the“No.1 Ginkgo”has laid an important foundation for the practical development of the quantum internet at the telecom band.
