Abstract
Quantum estimation of the operators of a system is investigated by analyzin g its Liouville space of operators. In this way it is possible to easily de rive some general characterizations for the sets of observables (i.e., the possible quorums) that are measured for the quantum estimation. In particul ar we analyze the reconstruction of operators of spin systems. (C) 2000 Els evier Science B.V. All rights reserved.
