Color codes are a class of topological codes that have come into prominence in the recent years. Like the surface codes the codespace defined by them can be associated to the degenerate ground state of a local Hamiltonian. In addition they can be designed to have an extended set of transversal encoded gates (compared to surface codes) increasing their appeal for fault tolerant quantum computation. In this paper we generalize the color codes to arbitrary prime power alphabet. We show that in the… CONTINUE READING
