摘  要:在量子精密测量和量子信息处理中,多模式量子纠缠态构成的量子网络是提升灵敏度和处理性能的关键部分,已在实验中初步展示了其优越性,并有望成为近期得到实用的技术。本文从连续变量系统中的量子态出发,简要介绍了压缩态的基本概念、制备与测量方式,同时介绍了多模式系统的相关概念与性质,并着重介绍了基于连续变量的多模式纠缠态的制备方案和进展,最后对量子网络的应用前景进行了展望。Significance Quantum entanglement,a crucial resource in quantum information science,describes a unique type of quantum correlation system.When two or more subsystems are entangled,their states are inseparable.The measurement results of this entangled system exhibit correlations that are fundamentally different from classical statistics,reflecting the non-local nature of quantum entanglement.In recent years,the rapid advancement of quantum information science has deepened our understanding of the interplay between quantum systems and information science.The concept of a quantum network has emerged in academic circles.A quantum network typically consists of multiple interconnected qubits.Nodes within the quantum network are responsible for generating,processing,and storing quantum information.These nodes are connected through quantum correlation or entanglement channels,enabling highfidelity quantum state transmission and distributing entanglement across the network.Quantum entanglement is a key resource for constructing quantum networks and realizing quantum communication,quantum computing,and quantum precision measurement.To meet the demands of complex quantum information processing and quantum network construction,generating and regulating large-scale quantum entangled states across multimode of light,i.e.,multimode quantum entanglement,has become a significant research challenge in quantum information science.Progress This review will focus on theoretical and experimental research regarding the preparation of quantum entangled networks,with a particular emphasis on continuous variable quantum optical systems.We provide an overview of three primary technical pathways for preparing the squeezed states in continuous variable quantum optics including optical parametric oscillator,parametric four-wave mixing,and related integrated quantum optical platforms.One of the most used approaches for preparing multimode entangled states involves using the optical beam splitter network to couple multiple squeezed sources.Howe
