Canonical Divergence for Flat α-Connections: Classical and Quantum

  title={Canonical Divergence for Flat $\alpha$-Connections: Classical and Quantum},
  author={Domenico Felice and Nihat Ay},
A recent canonical divergence, which is introduced on a smooth manifold M endowed with a general dualistic structure (g,∇,∇*), is considered for flat α-connections. In the classical setting, we compute such a canonical divergence on the manifold of positive measures and prove that it coincides with the classical α-divergence. In the quantum framework, the recent canonical divergence is evaluated for the quantum α-connections on the manifold of all positive definite Hermitian operators. In this…

A Novel Approach to Canonical Divergences within Information Geometry

A natural definition of a canonical divergence is proposed for a general, not necessarily flat, M by using the geodesic integration of the inverse exponential map, which reduces to the known canonical divergence in the case of dual flatness.

Canonical Divergence for Measuring Classical and Quantum Complexity

A new canonical divergence is put forward for generalizing an information-geometric measure of complexity for both classical and quantum systems and it is proved that the same divergence reduces to the quantum relative entropy, which quantifies many-party correlations of a quantum state from a Gibbs family.

Duality versus Dual Flatness in Quantum Information Geometry

We investigate questions in quantum informationgeometry which concern the existence and nonexistence of dual and dually flat structures on stratified sets of density operators on finite-dimensional

Differential Geometrical Aspects of Quantum State Estimation and Relative Entropy

In this article, we treat the space S of finite-dimensional positive density operators (quantum states) in a differential geometrical viewpoint. We suppose that a generalized covariance for arbitrary

Information geometry has emerged from the study of the invariant structure in families of probability distributions. This invariance uniquely determines a second-order symmetric tensor g and

Information geometry of divergence functions

This article studies the differential-geometrical structure of a manifold induced by a divergence function, which consists of a Riemannian metric, and a pair of dually coupled affine connections, which are studied in information geometry.


We show that, for each value of α∈(-1, 1), the only Riemannian metrics on the space of positive definite matrices for which the ∇(α) and ∇(-α) connections are mutually dual are matrix multiples of
