China has achieved major scientific accomplishments since embarking in 2001 on a journey to harness the vast potential of quantum mechanics in information security and military applications. Chinese scientists claimed success in satellite-based entanglement distribution in June 2017. Three months later, in September 2017, the 2,000-kilometer Quantum Communication Line between Shanghai and Beijing opened the world’s first trunk line of secure quantum telecommunications. China’s political leadership has demonstrated its interest and support in this very expensive endeavor, owing to the strategic and military applications of quantum cryptography, quantum computing, and quantum metrology for highly secure communications, stealth submarine operations, and military code breaking. This article explores the rapid development and evolution of research in quantum communications in China, the critical role of political leadership, and the immense opportunities it holds in the military domain.

With the development of technology, quantum technology with enormous military value has become a key technology related to national information security in the application and development of communication systems. The application of quantum communication technology in military and civilian research is of great significance for China’s future information network construction, as well as the safety of people’s lives and property. One need to increase investment in technology, increase investment in technology, and establish a sound policy system and institutional mechanisms. Only by increasing the promotion of this project can one further promote the development of military civilian integration of quantum communication technology in China and gradually establish a strong quantum communication information network. This article introduced the principles and development of quantum communication, and verified through simulation experiments that quantum technology communication has a lower bit error rate and better performance compared to traditional communication systems.
