    "abstract": "In a recent paper, Buscemi and al. defined a notion of clean positive\noperator valued measures (POVMs). We here characterize which POVMs are clean in\nsome class that we call quasi-qubit POVMs, namely POVMs whose elements are all\nrank-one or full-rank. We give an algorithm to check whether a given\nquasi-qubit POVM satisfies to this condition. We describe explicitely all the\nPOVMs that are clean for the qubit. On the way we give a sufficient condition\nfor a general POVM to be clean.",
