Abstract

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
