Abstract:

The number of patent applications, application trend, applicants, provincial and municipal distribution and subdivision technology field distribution in the field of quantum communication in China are analyzed. So, the overall picture of the patent distribution in the field of quantum communication in China can be shown. By comparing the number of patent claims, the current patent protection scope and patent quality are given. At last, the suggestions on the research and development of quantum communication technology and patent layout are put forward, and the industrialization prospect of quantum communication from the perspective of patent are analyzed.

Key words: quantum communication, quantum key distribution, patent layout
