Paper Abstract

Notion of distance between quantum states is reviewed using Hellinger distance between probability distributions and classical formulations of quantum mechanics based on tomography scheme. The Hellinger distances between the states of damped oscillator (considered in the frame of Caldirola-Kanai model) with delta-kicked frequencies in the regime of weak and strong damping, between the photon number distribution functions in SRS process, and between spin tomograms are considered.
