Characterization of classical statistical model for quantum parametric model
Jun Suzuki (UEC)
Abstract (in Japanese) (See Japanese page) 
(in English) Several equivalent conditions characterizing classical models are obtained for a parametric family of quantum states. Three different characterizations of the classical model are analyzed based on properties of the tangent space, quantum Fisher information matrices, and asymptotic bounds (the Holevo bound). We also show that a quantum statistical model in which all quantum logarithmic derivative operators commute with each other does not coincide with the classical model in general.
