On-chip generating, controlling and detecting quantum states of light with largescale silicon-photonic circuits opens the way to realizing complex quantum technologies for applications in the fields of computing, simulation and communication. In this talk we present recent progress in large-scale integrated photonic circuit for quantum information processing. We will discuss a large-scale silicon-photonic device that is able to generate, manipulate and measure multidimensional entanglement with high controllability and universality. The generation and manipulation of four-photon genuine multipartite entanglement and intra-chip/ inter-chip quantum teleportation have been realized in programmable devices. We will further show the demonstrations of scattershot and Gaussian Boson sampling up to eight photons states in a single silicon device.
