    "abstract": "We show how to perform reversible universal quantum computation on a\ntranslationally invariant pure state, using only global operations based on\nnext-neighbor interactions. We do not need not to break the translational\nsymmetry of the state at any time during the computation. Since the proposed\nscheme fulfills the locality condition of a quantum cellular automata, we\npresent a reversible quantum cellular automaton capable of universal quantum\ncomputation.",
