    "abstract": "We present a scheme in which an ion trap quantum computer can be used to make\narbitrarily accurate measurements of the quadrature phase variables for the\ncollective vibrational motion of the ion. The electronic states of the ion\nbecome the `apparatus\u0027, and the method is based on regarding the `apparatus\u0027 as\na quantum computer register which can be prepared in appropriate states by\nrunning a Fourier transform algorithm on the data stored within it. The\nresolution of the measurement rises exponentially with the number of ions used.",
