Abstract

Abstract: Using the DWPI database as the information source, the statistics of the number of patent applications and PCT applications in the field of quantum communication in various countries are given, the annual growth trend of global quantum communication technology patent applications and the distribution of IPC classification numbers are given, and the global distribution of the main applicants for quantum communication technology patents within the scope and the tracking of their key patent applications are tracked. Based on the development status of quantum communication technology patent, the technological evolution trend in the field of quantum communication is discussed and suggestions for patent application and protection are also proposed.

Key words: quantum communication, quantum key, patent
