Uncertainty relations with the variance and the quantum Fisher information based on convex decompositions of density matrices
We present several inequalities related to the Robertson-Schrödinger uncertainty relation. In all these inequalities, we consider a decomposition of the density matrix into a mixture of states, and use the fact that the Robertson-Schrödinger uncertainty relation is valid for all these components.
