摘要/Abstract

摘要：

量子互联网将量子计算、量子测量与通信相融合，可谓是量子信息技术演进的未来目标。然而，量子力学规律的限制，例如量子不可克隆、量子纠缠与测量坍塌等，对网络的网络功能、协议设计以及传输与中继等方面提出了新的挑战。首先介绍了量子互联网的基本概念与发展路径，考虑量子通信特性与经典通信的不同之处，从量子物理设备、网络协议、量子退相干与量子中继等方面对实现量子互联网的关键技术进行总结，并对量子互联网的发展进行了展望与建议。

关键词: 量子互联网, 量子通信, 关键技术

Abstract:

The quantum Internet integrates quantum computing, quantum measurement and communication, which can be described as the future goal of the evolution of quantum information technology.However, due to the restrictions of the laws of quantum mechanics, such as quantum teleportation, quantum entanglement, quantum measurement and non-cloning, which all pose new challenges to the quantum networking design.The basic concepts and development paths of the quantum Internet were firstly introduced, and the implementation differences between the classical network and the quantum network were explained.Considering the difference between quantum communication and the traditional communication, the key technologies for realizing the quantum Internet including the quantum physical devices, networking protocol, quantum decoherence and quantum relay were introduced, and finally the prospect and suggestions for developing quantum Internet was presented.

Key words: quantum Internet, quantum communication, key technology
