WebNov 1, 2010 · So when Cov (d α) and the geometric phase are both zero, we recover the Fisher classical information metric, namely (14) h X = 1 4 F. In general, we have that the Fisher classical information metric F / 4 is strictly dominated by the quantum Riemannian metric g. In the general case (d α ≠ 0) h X coincides with the Fisher quantum … WebAt first we consider the Fisher-Rao metric as a Riemannian metric on the Statistical Manifold of the Gaussian distributions.
