AI 中文摘要
在本论文中，我们从理论上提出了一种产生涡旋光学压缩的替代方案，该方案基于相干制备介质中的拉曼散射过程，不同于诸如参量下转换和四波混频等方法。我们的分析表明，通过调整相关系统参数，输入控制场和产生的信号场都可以表现出压缩，并且在相同条件下控制场表现出更大程度的压缩。我们进一步证明了在一系列调谐参数范围内存在最佳压缩值，突出了所提出方案的灵活性和稳健性。这些发现可能为连续变量涡旋光学压缩提供新的参考，并在量子信息处理、量子精密测量和量子传感等领域具有潜在应用。
英文摘要
In this Letter, we theoretically propose an alternative scheme for generating vortex optical squeezing, based on the Raman scattering process in a coherently prepared medium, distinct from approaches such as parametric down-conversion and four-wave mixing. Our analysis reveals that both the input control field and the generated signal field can exhibit squeezing upon adjusting the relevant system parameters, with the control field exhibiting a greater degree of squeezing under identical conditions. We further demonstrate the existence of optimal squeezing values over a range of tuning parameters, highlighting the flexibility and robustness of the proposed scheme. These findings may offer a new reference for continuous-variable vortex optical squeezing and possess potential applications in domains such as quantum information processing, quantum precision measurement, and quantum sensing.
