  內容提要: 

  Quantum information science aims to exploit the unique properties of quantum mechanics such as superposition and entanglement for enhanced ways of information processing. Photons appear to be the obvious choice for quantum  communication, and a clean system for demonstrating quantum computing primitives. A major challenge to increasingly climb up the number of useful qubits. To this end, I will describe two parallel paths toward scalable photonic quantum technologies in  this talk. One is using nonlinear optics and multiple degrees of freedom of a single  photons. The other one is generating deterministic, and highly indistinguishable  single photons from a quantum dot. The multi-photon setups offers a versatile  workhorse for optical quantum information processing, such as multiple property  teleportation, and quantum computing for big data.
