Preface: celebrating the 60th anniversary of the University of Science and Technology of China

正The University of Science and Technology of China(USTC)is a prominent institution with an excellent reputation for education and innovation that resonates across the world.The university holds a special place in history.It was established by the Chinese Academy of Sciences(CAS)in1958 to meet China’s science and technology needs and increase the country’s international competitiveness.Throughout its history we have focused on frontier areas of science and technology and educated top leaders in science and technology for China and the world.     

Nonadiabatic holonomic quantum computation based on nitrogen-vacancy centers

正Because of quantum superposition,quantum computation can solve many problems,such as factoring large integers[1]and searching unsorted databases[2,3],much faster than classical computation.To realize practical quantum computation and then gain the desired advantages,a universal set of quantum gates with sufficiently high fidelities are needed.However,various inevitable errors reduce the gate fidelities and finally collapse the computation results,which makes the realizations of quantum computation very challenging.To relax     

Metal–Organic Framework (MOF)-Derived Carbon-Mediated Interfacial Reaction for the Synthesis of CeO2−MnO2 Catalysts

CeO₂-based catalysts are widely studied in catalysis fields. Developing one novel synthetic approach to increase the intimate contact between CeO₂ and secondary species is of particular importance for enhancing catalytic activities. Herein, an interfacial reaction between metal–organic framework (MOF)-derived carbon and KMnO₄ to synthesize CeO₂−MnO₂, in which carbon is derived from the pyrolysis of Ce-MOFs under an inert atmosphere, is described. The MOF-derived carbon is found to restrain the growth of CeO₂ crystallites under a high calcination temperature and, more importantly, intimate contact within CeO₂/C is conveyed to CeO₂/MnO₂ after the interfacial reaction; this is responsible for the high catalytic activity of CeO₂−MnO₂ towards CO oxidation.
