Product-State Manifolds for M Quantum Systems with N Levels using the Fano form and the Induced Euclidean Metric
Fotios D. Oikonomou
In quantum mechanics separable states can be characterized as convex combinations of product states whereas non-separable states exhibit entanglement. Quantum entanglement has play…
Towards an Information Geometric characterization/classification of Complex Systems. II. Critical Parameter values from the (c,d)-manifold
Demetris P. K. Ghikas, Fotios D. Oikonomou
In our previous paper (I) we derived information geometric objects from the two parameter generalized entropy of Hanel and Thurner (2011), using the c,d parameters as labels of the…
Towards an Information Geometric characterization/classification of Complex Systems. I. Use of Generalized Entropies
Demetris P. K. Ghikas, Fotios Oikonomou
Using the generalized entropies which depend on two parameters we propose a set of quantitative characteristics derived from the Information Geometry based on these entropies. Our…
A new information metric and a possible higher bound for a class of measurements in the Quantum Estimation Problem
Demetris P. K. Ghikas, Fotios Oikonomou
Information metrics give lower bounds for the estimation of parameters. The Cencov-Morozova-Petz Theorem classifies the monotone quantum Fisher metrics. The optimum bound for the q…
