    "abstract": "We outline a toolbox comprised of passive optical elements, single photon\ndetection and superpositions of coherent states (Schrodinger cat states). Such\na toolbox is a powerful collection of primitives for quantum information\nprocessing tasks. We illustrate its use by outlining a proposal for universal\nquantum computation. We utilize this toolbox for quantum metrology\napplications, for instance weak force measurements and precise phase\nestimation. We show in both these cases that a sensitivity at the Heisenberg\nlimit is achievable.",
