    "abstract": "The phase resolution of interferometers is limited by the so-called\nHeisenberg limit, which states that the optimum phase sensitivity is inversely\nproportional to the number of interfering particles N, a 1/sqrt{N} improvement\nover the standard quantum limit. We have used simulated annealing, a global\noptimization strategy, to systematically search for quantum interferometer\ninput states that approach the Heisenberg limited uncertainty in estimates of\nthe interferometer phase shift. We compare the performance of these states to\nthat of other non-classical states already known to yield Heisenberg limited\nuncertainty.",
