    "abstract": "We propose a detection scheme for measuring the overlap of the quantum state\nof a weakly excited traveling-field mode with a desired reference quantum\nstate, by successive mixing the signal mode with modes prepared in coherent\nstates and performing photon-number measurements in an array of beam splitters.\nTo illustrate the scheme, we discuss the measurement of the quantum phase and\nthe detection of Schrodinger-cat-like states.",
