    "abstract": "We describe some applications of quantum information theory to the analysis\nof quantum limits on measurement sensitivity. A measurement of a weak force\nacting on a quantum system is a determination of a classical parameter\nappearing in the master equation that governs the evolution of the system;\nlimitations on measurement accuracy arise because it is not possible to\ndistinguish perfectly among the different possible values of this parameter.\nTools developed in the study of quantum information and computation can be\nexploited to improve the precision of physics experiments; examples include\nsuperdense coding, fast database search, and the quantum Fourier transform.",
