Large-scale integrated quantum photonics (Plenary Presentation)

Harnessing integrated quantum photonic circuits for the generation, manipulation, and detection of quantum states of light offers a pathway towards implementing advanced quantum technologies for applications spanning quantum computation, quantum simulation, and quantum communication. In this presentation, we will show recent advancements in the large-scale integrated photonic devices and circuits for quantum computation, networking, and simulations. Our discussion will delve into the on-chip processes involved in creating, manipulating, and measuring complex entanglement structures, such as multidimensional and multiphoton entanglement. We will discuss quantum computing and networking with integrated photonics, highlighting several aspects of chip-based entanglement distribution, teleportation, Gaussian Boson sampling, qudit-based and cluster-state quantum computations. We will also discuss photonic simulations of topological physics on a lattice of coupled microresonators, by which we have observed topologically-protected entanglement and fast topological non-Hermitian phase transitions, and we implemented a fully programmable photonic insulator within this framework.
