Quantum Fisher Information: Variational principle and simple iterative algorithm for its efficient computation

Quantum Physics 2013-12-06 v1

Abstract

We derive a new variational principle for the quantum Fisher information leading to a simple iterative alternating algorithm, the convergence of which is proved. The case of a fixed measurement, i.e. the classical Fisher information, is also discussed.
