    "abstract": "With growing success in experimental implementations it is critical to\nidentify a \"gold standard\" for quantum information processing, a single measure\nof distance that can be used to compare and contrast different experiments. We\nenumerate a set of criteria such a distance measure must satisfy to be both\nexperimentally and theoretically meaningful. We then assess a wide range of\npossible measures against these criteria, before making a recommendation as to\nthe best measures to use in characterizing quantum information processing.",
