Holographic metasurfaces and their applications have garnered significant attention owing to their role in polarization control. In this study, we demonstrate that the quantum properties of holographic metasurfaces can be obtained by quantum state tomography (QST) and quantum process tomography (QPT). We perform QST to obtain the experimental output states by extracting information from holograms encoded on the holographic metasurface, and develop a QPT-based method to estimate the quantum process of the metasurface. The theoretical output states derived from the estimated quantum process are in good agreement with the experimental output states, proving the effectiveness of our method. Our work not only provides theoretical and experimental analysis for understanding the quantum properties of holographic metasurfaces, but also paves the way for the application of holographic metasurfaces in quantum field.

全息超表面及其应用因其在偏振控制中的作用而备受关注。在这项研究中，我们证明了全息超表面的量子特性可以通过量子态断层扫描 (QST) 和量子过程断层扫描 (QPT) 获得。我们执行 QST 通过从全息超表面上编码的全息图中提取信息来获得实验输出状态，并开发一种基于 QPT 的方法来估计超表面的量子过程。从估计的量子过程得出的理论输出状态与实验输出状态非常吻合，证明了我们方法的有效性。我们的工作不仅为理解全息超表面的量子特性提供了理论和实验分析，
