摘　　要：光纤中的三阶非线性效应可用于多种量子态的制备,为量子信息的研究提供了一种有效的工具。光纤波导结构具有非线性作用长度长以及传输损耗低的特点,这可使非线性效应显著增强;而且波导结构中所产生的量子态具有纯净的空间模式,这有利于量子态的收集和操控;此外现有光纤和光纤器件具有工艺成熟、稳定高效和成本低廉的特点,这使得基于光纤的量子光源具有小型化、低成本以及可与现有光纤网络高效集成的优势。对基于光纤的量子关联光子对的制备工作进行回顾,主要内容包括利用不同种类的光纤实现不同波段、不同频谱特性的关联光子对,以及不同自由度的纠缠关联光子对。The third-order nonlinear effect in optical fiber can be used to prepare a variety of quantum states,which provides an effective tool for the study of quantum information.Because of the long interacting length and low transmission loss,the waveguide structure of optical fibers can significantly enhance the nonlinear effects.On the other hand,the quantum states originate from the waveguide have a well-defined pure spatial mode,which is helpful for the collection and manipulation of the quantum states.Moreover,the commercially available fiber components are mature,effective,and low-priced.Therefore,there is a prospect of developing all fiber quantum light sources,which are not only miniaturized and low-cost,but also compatible with the optical fiber network.In this paper,we review the generation of quantum correlated photon pairs in different kinds of optical fibers,including the photon pairs in different wavelength bands and with different spectral properties,and entangled photon pairs in different degrees of freedoms.
