    "abstract": "Quantum estimation of the operators of a system is investigated by analyzing\nits Liouville space of operators. In this way it is possible to easily derive\nsome general characterization for the sets of observables (i.e. the possible\nquorums) that are measured for the quantum estimation. In particular we analyze\nthe reconstruction of operators of spin systems.",
