Abstract: Optically active quantum dot represents a unique quantum system that combines solid state spin qubits with coherent optical transitions. It performs as a natural link between the study of nanoscience, atomic quantum optics and quantum information. Particularly in the frame of quantum information, my talk will focus on the optical manipulation of a quantum dot spin. Based on that, I will report the creation of entanglement between a flying photon and a semiconductor quantum dot spin, acting as a key step towards a quantum network with nodes consisting of semiconductor spin qubits. In the end, I will make a prospect and talk about where we stand in the quantum information application with optically active quantum dot.
