Multi-Photon Interferometry

Principal investigator
Introduction

We are devoted to develop and use advanced photonic quantum systems for investigations and applications in quantum information science. One of our aims is to increase the number of entangled photons, which are based on spontaneous parametric down-conversion and photonic interferometry. The other aim is to develop ultra-loss integrated linear optics, which has wide applications in quantum information processing such as bosonsampling, quantum random walk, quantum simulation and quantum computation.
