【摘要】 具有反聚束特性的非经典光场是量子信息与量子光学的重要资源。基于非线性光学的量子干涉效应，通过将压缩真空态与特定相位的相干态在光学分束器上合成的方法获得平移压缩真空态，对压缩度和相干分量进行独立控制以获得反聚束。本文结合实验系统参数，理论研究了压缩真空态的压缩度和相干态的幅度对实验产生反聚束光场的影响。在最优化平移条件下，我们分析了系统总效率、背景噪声，以及Hanbury Brown-Twiss（HBT）与Double HBT测量方法对反聚束光场g^（2）（0）测量的影响，并讨论了误差为零处相应量子态的g^（2）（0）值和平均光子速率。更多还原

【Abstract】 Nonclassical light fields with a property of strong antibunching are important resources for quantum information and quantum optics. Based on the quantum interference effect of nonlinear optics, a strong antibunching light can be obtained by superposing the squeezed vacuum state and the coherent state of a specific phase on an optical beam splitter. Squeezing degree and displacement can be independent adjustments for optimal antibunching. In this paper, combined with the parameters of the experiment system, we have theoretically studied the influence of the squeezing degree of the squeezed vacuum state and the amplitude of the coherence state on the generating of an antibunching light. Under the optimal displacement condition, analyzed the influence of the measurement of g(2)(0) of the antibunching light with system total efficiencies、background noises、Hanbury Brown-Twiss(HBT) and Double HBT measurement method. Discussed the value of g(2)(0) and average photon rate of the quantum state where the error is 0.更多还原
