Research Profile

     Guo Guangcan, born in 1942 in Hui’an, Fujian Province, is currently an academician, professor and doctoral supervisor at the University of Science and Technology of China (USTC). Prof. Guo graduated from the Department of Radio-Electronics at USTC in 1965, and joined the faculty of USTC that year. Now he is a professor at USTC and Director of the Key Laboratory of Quantum Information, Chinese Academy of Sciences (CAS). Prof. Guo was elected Academician of the Chinese Academy of Sciences in 2003.

    Guo has long been engaged in the teaching and research work on optics and physics and has made outstanding contributions in teaching and talent cultivation. He has been named as one of the national outstanding teachers by the Ministry of Education. He has obtained a series of results of international standards in scientific research and has been awarded the title of advanced workers by the Chinese Academy of Sciences (CAS)
     
     Prof. Guo is now the Chief Expert of the directional project of the Chinese Academy of Sciences (CAS) and the Chief Scientist of the porject of “Quantum Communication and Quantum Information Technology” supported by the National Basic Research Program of China (also known as the “973” Program) under the Ministry of Science and Technology of China. He has published over 210 major papers, including four PRL papers and 29 PRA papers, among which 168 were indexed by SCI with a total of citations exceeding 760 times and citations by others exceeding 576 times. Besides, he has published or translated 11 monographs. Prof. Guo has graduated 13 Ph.D. students, and 29 master’s degree students, among whom one has entered the list of “Top 100 National Excellent Doctoral Dissertations of China” and one has won support from the National Science Foundation for Distinguished Young Scholars of China.

     Prof. Guo has been devoting himself to the researches on quantum optics, non-linear optics and quantum information. He proposed the principle of probabilistic quantum clone and derived the formula of the maximum probability of clone, which, known as “Duan-Guo probabilistic clone machine” and “Duan-Guo limit”, has become the basis for one of the two different kinds of quantum clone machine. He experimentally realized the two kinds of quantum clone machine—probabilistic and universal quantum clone machine, and then proved the related theorem. He found the existence of “coherence-preserving states” which can protect quantum states from decoherence. Based on this finding, he proposed quantum error avoiding code, which is one of the three different kinds of quantum code, and proven it experimentally. He present a novel quantum information processor, which can effectively reduce the influence of the decoherence in cavities, and realized it experimentally as well. He realized the quantum key distribution (QKD) between two long distant sites experimentally and then accomplished the secure communication system based on quantum cryptography, which can transfer active pictures securely. He also proposed a new encryption scheme. He performed an all-or-nothing-type K-S experiment to verify whether non-contextual hidden variables or quantum mechanics theory is right, and observed that the results strongly agree with quantum mechanics. He explored the interesting characteristic of the odd and even coherent state, etc.
