Research on method for adding new friends to instant messaging system based on SIP in quantum communication network

Abstract

Quantum communication is a new interdisciplinary branch of science which has been developing during the past two decades, which is a new research field combining quantum theory and information theory. Quantum communication is characterized by some features such as being highly efficient and absolutely safe, which is now a hot research area in quantum physics and information science around the world. In the paper, the solution for adding new friends list to instant messaging system based on SIP protocol is put forward through modifying SIP source code and configuration files as well as uploading friends list by utilizing curl command in quantum communication network.
