题目（Title）：Single and multiple quantum dots made from semiconductor nanostructures for quantum information processing

摘要 (Abstract)：Semiconductor quantum dots are among the key technology platforms for solid-state based quantum information processing. In this talk, he will report their recent works on the realizations of single, double and triple quantum dots in semiconductor heterostructures and nanowires, and on the transport studies of spin and change states, as well as spin correlations, in the devices，particularly the results of quantum dot devices made from InGaAs/InP heterostructures, InAs nanowires, and InSb nanowires. The observations of novel physics phenomena, such as spin-correlation induced conductance suppression, g-factor and spin-orbit interaction fluctuations, coherent charge transfer between remote quantum dots, in these devices will be presented and discussed.
