Recently, the quantum information field represented by quantum computing, quantum communication, and quantum measurement has continued to be active. It has become an important trend in basic research exploration, disruptive technology innovation and future industry transformation. Therefore, clarifying the development trend of quantum information field is of great value for China to build a world's science and technology power. Firstly, this paper introduces the relevant concepts and research in the quantum information field, then analyzes the quantum strategy layout of the United States, the European Union, the United Kingdom, Japan and China. Finally, it shows the research and development trend through the multi-dimensional bibliometric analysis of papers and patents in the quantum information field. At present, the quantum information field is in a rapid development stage, and international scientific and technological powers attach great importance to policy layout, capital investment, talent introduction and international cooperation in the field, among which the United States has the most advantage. China has entered the core position in the fields of quantum communication and quantum computing. In the future, it is necessary for China to accelerate the strategic deployment, actively attract and retain quantum information talents, and deeply promote the industry-university-research cooperation innovation in the quantum information field.
