Information Geometrical Characterization of Quantum Statistical Models in Quantum Estimation Theory
In this paper, we classify quantum statistical models based on their information geometric properties and the estimation error bound, known as the Holevo bound, into four different classes: classical, quasi-classical, D-invariant, and asymptotically classical models. We then characterize each model...
