Operation parameters of magnetic quantum cellular automata are evaluated for the purposes of
reliable logic operation. The dynamics if nanomagnets is simulated via Landau-Lifshitz-Gilbert equations with stochastic magnetic field corresponding to thermal fluctuations. It is found that in the macrospin approximation the switching speed does not change under scaling of both size and distances between nanomagnets. Thermal fluctuations put a limitation on the size of nanomagnets, since the gate error rate excessive for nanomagnets smaller than 200nm at room temperature.
