    "abstract": "We present a quantum computing scheme with atomic Josephson junction arrays.\nThe system consists of a small number of atoms with three internal states and\ntrapped in a far-off resonant optical lattice. Raman lasers provide the\n\"Josephson\" tunneling, and the collision interaction between atoms represent\nthe \"capacitive\" couplings between the modes. The qubit states are collective\nstates of the atoms with opposite persistent currents. This system is closely\nanalogous to the superconducting flux qubit. Single qubit quantum logic gates\nare performed by modulating the Raman couplings, while two-qubit gates result\nfrom a tunnel coupling between neighboring wells. Readout is achieved by tuning\nthe Raman coupling adiabatically between the Josephson regime to the Rabi\nregime, followed by a detection of atoms in internal electronic states.\nDecoherence mechanisms are studied in detail promising a high ratio between the\ndecoherence time and the gate operation time.",
