    "abstract": "We discuss the role of classical control in the context of reversible quantum\ncellular automata. Employing the structure theorem for quantum cellular\nautomata, we give a general construction scheme to turn an arbitrary cellular\nautomaton with external classical control into an autonomous one, thereby\nproving the computational equivalence of these two models. We use this\ntechnique to construct a universally programmable cellular automaton on a\none-dimensional lattice with single cell dimension 12.",
