Abstract:The technique of quantum information is a new developing field that involves both the quantum physics and the information science. It equips the information science with new principles and methods and ensures its persistent development. This paper introduces the backgrounds of quantum information technique and illustrates the strange functions dealing with information. It also gives a brief view to the international developing situation and prospect. The Chinese Academy of Science has given strong support to the subject of quantum information as an area with priority. We here introduce the main research results in this area that we have obtained in the recent years. Finally, we propose some suggestions on the further development of technique of quantum information in our academy and thus to induce more valued ideas.
