原标题：Optical quantum information processing with solid state
内容提要：
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.
