    "abstract": "We investigate the utility of non classical states of simple harmonic\noscillators (a superposition of coherent states) for sensitive force detection.\nWe find that like squeezed states a superposition of coherent states allows the\ndetection of displacement measurements at the Heisenberg limit. Entangling many\nsuperpositions of coherent states offers a significant advantage over a single\nmode superposition states with the same mean photon number.",
