Previously, simulating fluid dynamics on a quantum computer necessitated either accepting approximation errors or facing exponentially increasing computational demands with each step. Now, a new quantum lattice Boltzmann method utilises rotation collisions, systematically constructing unitary operations where non-unitary relaxation previously stood. This allows for reusable circuits in models like D2Q5, circumventing limitations of earlier approaches.
