报告摘要:	In this talk, I will describe several experiments demonstrating simple quantum computation primitives using multi-photon entanglement and semiconductor quantum dots. I will start with a general introduction to the field of linear optical quantum computing, and move to experiments using parametric down-conversion that have demonstrated six-, eight-photon entanglement and Shor's factoring algorithm, followed by a discussion of the challenges of making this approach scalable. In the second part of the talk, I will switch to solid-state quantum system - GaAs/InAs quantum dots, and show our experimental efforts in generating highly indistinguishable resonance fluorescence single photons which find wide applications in optical quantum computing, probing spin dynamics, and single-shot optical spin readout.
