科学家提出广义量子相干态的空间光模式类比
近日，墨西哥帕丘卡理工大学的B. M. Rodríguez-Lara与美国路易斯安那州立大学的O. S. Magana-Loaiza等人合作并取得一项新进展。经过不懈努力，他们提出广义量子相干态的空间光模式类比。相关研究成果已于2024年9月26日在国际知名学术期刊《物理评论A》上发表。
该研究团队利用光模式的空间自由度，为厄米-高斯模式和拉盖尔-高斯模式构建了广义量子相干态的光学类比。该光学类比保留了其量子对应态的统计特性，这些特性编码在其振幅和相位分布中。研究人员探讨了提供广义平移、旋转和压缩相干态的三种基本对称性。鉴于压缩态在探测物质方面的广泛关注，研究人员相信这里引入的光学类比对于光学传感具有重要意义。
具体而言，该研究中空间模式的单粒子性质使其成为探测光敏材料的鲁棒候选者。总之言之，这一研究方法为模仿量子领域已存在的光学测量和传感协议打开了大门，并通过经典光学类比促进了对量子态集合的进一步探索。

Abstract: We use the spatial degree of freedom of light modes to construct optical analogs of generalized quantum coherent states for Hermite- and Laguerre–Gauss modes. Our optical analogs preserve the statistical properties of their quantum counterparts, encoded in their amplitude and phase distributions. We explore three basic symmetries that provide generalized displaced, rotated, and squeezed coherent states. Given the substantial interest in squeezed states for probing matter, we believe that the optical analogs introduced here have significant implications for optical sensing. Specifically, the single-particle nature of our spatial modes makes them robust candidates for sensing photosensitive materials. Overall, our approach opens the door to optical metrology and sensing protocols that mimic those already existing in the quantum realm, and facilitates further exploration of the quantum state zoo through classical optical analogs.
