    "abstract": "The Mott insulator state created by loading an atomic Bose-Einstein\ncondensate (BEC) into an optical lattice may be used as a means to prepare a\nregister of atomic qubits in a quantum computer. Such architecture requires a\nlattice commensurately filled with atoms, which corresponds to the insulator\nstate only in the limit of zero inter-well tunneling. We show that a lattice\nwith spatial inhomogeneity created by a quadratic magnetic trapping potential\ncan be used to isolate a subspace in the center which is impervious to\nhole-hoping. Components of the wavefunction with more than one atom in any well\ncan be projected out by selective measurement on a molecular photo-associative\ntransition. Maintaining the molecular coupling induces a quantum Zeno effect\nthat can sustain a commensurately filled register for the duration of a quantum\ncomputation.",
