开发了一个量子启发的框架，用于大气中的偏振辐射传输，以联合模拟多次散射、吸收和发射过程。辐射场由斯托克斯矢量表示，并使用在三维均匀分布的天顶角和方位角矢量上的n方向二维空间晶格进行离散化。该量子计算系统的公式基于格子玻尔兹曼方法，其中包含了基于物理的偏振相位矩阵。实现了一个经典晶格求解器，其采用与量子算法相同的空间和角度离散化及物理建模。相应的量子算法使用IBM Qiskit量子模拟器进行评估，从而能够直接与经典模拟参考进行数值精度比较。结果表明，完全基于物理的偏振辐射传输可以嵌入到量子晶格框架中，这为可扩展的量子大气辐射传输和未来的量子气候建模提供了初步基准。

英文摘要

A quantum inspired framework was developed for polarized radiative transfer in the atmosphere to jointly model multiple scattering, absorption, and emission processes. The radiative field is represented by the Stokes vector and discretized using an n-directional two-dimensional spatial lattice on 3-dimensional uniformly distributed zenith and azimuth angular vectors. The formulation of this quantum computation system is based on the Lattice Boltzmann Method, which incorporates a physics-based polarized phase matrix. A classical lattice solver employing identical spatial and angular discretization and physical modeling as in quantum algorithm is implemented. The corresponding quantum algorithm is evaluated using the IBM Qiskit quantum simulator, enabling direct comparison of numerical accuracy to a classical simulation reference. The results demonstrate that fully physics-based polarized radiative transfer can be embedded within a quantum lattice framework, which provides an initial benchmark toward scalable quantum atmospheric radiative transfer and future quantum climate modeling
