This research presents a quantum-inspired lattice framework for modeling polarized radiative transfer in the atmosphere, validating its numerical accuracy against classical solvers using IBM Qiskit. The study establishes an initial benchmark for embedding physics-based atmospheric processes into quantum algorithms, paving the way for scalable quantum climate modeling. While the application targets environmental science, the core contribution lies in advancing quantum algorithmic formulations for complex physical systems.
A Quantum-Inspired Two-Dimensional Lattice Polarized Radiative Transfer Simulator
arXiv:2609.23057v1 Announce Type: new Abstract: 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
