Research Profile

    Peng Xinhua, female, Doctorate of Science, born in June 1978, is a native of Xiangyin County, Hunan Province. She was admitted to the Department of Physics, Hunan Normal University in September 1994 and then was recommended for immediate admission to the Wuhan Institute of Physics and Mathematics of the Chinese Academy of Sciences (CAS) in 1998 to study for MS and Ph.D. degrees. In 2003, she received her Doctor of Science (D.Sc.) degree and became a recipient of the CAS Presidential Scholarship (Award of Merit). From August 2003 to August 2005, she undertook collaborative research as a Humboldt Fellow at the University of Dortmund, Germany. Then she continued her scientific research in Germany. In April 2008, she was introduced to work as a professor and Ph.D supervisor at the University of Science and Technology of China (USTC) under the “Hundred Talents” Program of UTSC.
     Professor Peng’s research is mainly focused on the experimental research work of quantum computation and quantum information processing of the spin system of magnetic resonance. Her research directions involve extensive research on quantum state preparation, quantum algorithms and quantum computing, quantum measurement, and other experimental and theoretical research on fundamental issues of quantum mechanics (such as the complementarity principle). Her research is also concerned with the application of quantum information technology to simulate important physical phenomena (such as quantum phase transition) in condensed matter physics, and the exploration of quantum information transmission and the new model of quantum computing (such as quantum adiabatic model).
