    "abstract": "We apply a Kennedy-type detection scheme, which was originally proposed for a\nbinary communications system, to interferometric sensing devices. We show that\nthe minimum detectable perturbation of the proposed system reaches the ultimate\nprecision bound which is predicted by Neyman-Pearson hypothesis testing. To\nprovide concrete examples, we apply our interferometric scheme to phase shift\ndetection by using coherent and squeezed probe fields.",
