Photon can be generated, manipulated and detected comparably easier than other physical systems (atom, superconductor and NMR etc), and can be transmitted in a long distance without coupling into environment. Photon therefore is a promising candidate for realising quantum information processing, including quantum enhanced communication, computation, simulation and metrology. However, a few limitations including phase stability, mode matching and loss that were thought to be only technical problems have become fundamental bottle necks preventing quantum information processing from realising in large scale and practical applications. Integrated photonics is an elegant way to solve the aforementioned problems. In this talk, I will give a brief overview of my work on quantum information processing based on integrated photonic circuits fabricated by UV laser direct writing. I will also introduce the progress of building femtosecond laser writing 2.0 and establishing the laboratory of Integrated Photonics and Quantum Information (IPQI) in Shanghai Jiao Tong University.
