    "abstract": "It is shown that classical control diagrams can be mapped one-to-one onto\nquantum path integrals over measurement amplitudes. To show the practical\nutility of this method, exact closed-form expressions are derived for the\ncontrol dynamics and quantum noise levels of a test mass observed by a\nFabry-Perot interferometer. This formalism provides an efficient yet rigorous\nmethod for analyzing complex systems such as interferometric gravity wave\ndetectors and magnetic resonance force microscopy (MRFM) experiments. Quantum\nlimits are conjectured for the sensitivity of interferometric observation of\ntest mass trajectories.",
