    "abstract": "The intrinsic unsharpness of a quantum observable is studied by introducing\nthe notion of resolution width. This quantification of accuracy is shown to be\nclosely connected with the possibility of making approximately repeatable\nmeasurements. As a case study, the intrinsic unsharpness and approximate\nrepeatability of position and momentum measurements are examined in detail.",
