Research Areas

My current research is focused on optoelectronic properties of semiductor quantum systems for quantum information processing and spintronics. Specifically, high efficient single-photon sources and single-photon detectors; initializing, coherent manipulating, detecting and scaling up the quantum bits based on the charge, exciton and spin in a single quantum systems; ultrafast spin dynamics and low temperature transport in semiconductor nanostructures; strong coupling between quantum dots and photonic crystal cavity or surface plasmon for quantum photonic network;
