USTC's Major Breakthrough in Quantum Computing Research


        The October 29 issue of Nature published the research results by the USTC team headed by Professor Du Jiangfeng in collaboration with R.B. Liu of the Chinese University of Hong Kong. By the electron spin resonance technique, the researchers have realized optimal dynamical decoupling in solid-state systems for the first time in the world, thereby greatly prolonging the electron spin coherence time. It is pointed out in the editor's summary that this work effectively maintains the quantum coherence of spins in solid materials, which is significant for the realization of solid-state spin quantum computing.

        An article in the column "News and Views" of the same issue points out:"The inevitable information loss of the quantum system limits their real-world applications. The study by Du Jiangfeng et al shows that, however, through the sophisticated pulse control, the adverse impact of the solid-state environment on the electronic quantum bits has been reduced to a minimum, thus significantly reducing the information loss of the quantum system. Their quantum coherence control technology has been proven to be an important resource in helping people to understand and effectively combat the quantum information loss, and its significance lies in greatly enhancing the performance of real physical systems, thus moving a big step towards the realization of quantum computing."



Highlight of USTC

On May 11, the Nature Publishing Group released Nature Publishing Index 2010 China, remarking “a dramatic rise in the quality of research being published by China”. University of Science and Technology of China is ranked 3rd of TOP 10 Institutions in Index 2010 China.
