Abstract
This article presents an encoding for the quantum Lattice Boltzmann method algorithm using Carleman linearization. In contrast to previous articles [C. Sanavio et al., AVS Quantum Sci. 6, 023802 (2024); Phys. Fluids 37, 037123 (2025)], the encoding used allows for local collision rules while keeping a higher probability to obtain the correct result, which is of the order of . The algorithm scales as at each time step with the number of lattice sites of the two-dimensional lattice and the number of channels with a constant number of qubits when using dynamical circuits.
