    "abstract": "It is shown that different distinguishability measures impose different\norderings on ensembles of $N$ pure quantum states. This is demonstrated using\nensembles of equally-probable, linearly independent, symmetrical pure states,\nwith the maximum probabilities of correct hypothesis testing and unambiguous\nstate discrimination being the distinguishability measures. This finding\nimplies that there is no absolute scale for comparing the distinguishability of\nany two ensembles of $N$ quantum states, and that distinguishability comparison\nis necessarily relative to a particular discrimination strategy.",
