报告摘要

One promising technique for working toward practical photonic quantum technologies is to implement multiple operations on a monolithic chip, for improving stability, scalability and miniaturization. In this talk, we will focus on the on-chip generation and manipulation of entangled photon-pair inside a single quadratic nonlinear photonic crystal (NPC). By the design of concurrent quasi-phase-matching processes, the spectrum and spatial entanglement can be shaped on demand, resulting in new applications in path-entanglement generation, two-photon focusing and beam-splitting, lensless quantum ghost imaging etc. The NPCs act as a key ingredient in integrated quantum information processing
