    "abstract": "We investigate the utility of non classical states of simple harmonic\noscillators, particularly a superposition of coherent states, for sensitive\nforce detection. We find that like squeezed states a superposition of coherent\nstates allows displacement measurements at the Heisenberg limit. Entangling\nmany superpositions of coherent states offers a significant advantage over a\nsingle mode superposition states with the same mean photon number.",
