On the Riemannian metric of α-entropies of density matrices

The Riemannian metric induced by quantum α-entropies is proven to be monotone under stochastic mappings on the set of density matrices. The length of tangent vectors is essentially the Wigner-Yanase-Dyson skew information in this setting.
