Abstract
We propose a quantum algorithmic protocol for calculating astrophysical opacities. Our implementation uses first- and second-quantized representations of interacting electronic and photonic subsystems and Hamiltonian simulation via the interaction picture. Inferring opacity from momentum-resolved measurements of the photonic register yields a direct relationship between qubit count and spectral range/resolution. Logical resource estimates for the classically challenging problem of solar iron opacity are comparable to another high-energy-density physics problem (Rubin et al., PNAS 121(3) (2024)).
