摘要

Since its first experimental demonstration,squeezed light has been the driving force to push forward the frontier of quantum optics[1].Recently,with the rapid development of quantum information science,the study of squeezed light has entered a new stage,aiming at real-world impact beyond proof-of-principle demonstra-tions[2,3].One prominent example is Laser Interferom-eter Gravitational-wave Observatory(LIGO),which uti-lizes base-band squeezed light to enhance its sensitivity,leading to the first observation of gravitational waves[4].In parallel,numerous studies are being pursued to lever-age squeezed light to generate large-scale cluster states,an essential resource for photonic quantum information processing[5,6].Such cluster states can have profound impact for both quantum computing and quantum net-works.The approach based on squeezed light is advanta-geous as it can be generated deterministically,in contrast to other probabilistic approaches.
