We analyze the Spin-Orbit mediated two and three qubit entanglement production in single layer graphene. We found the striking result that, within experimentally feasible parameter values, it is possible to thermally increase the two qubit quantum concurrence, even near room temperature. We also find a cooperative effect resulting from the interplay of scattering and SO coupling. The experimental and technologically relevant implementations are further discussed.
