Comments on "Stronger Uncertainty Relations for All Incompatible Observables"
arXiv:1502.04853
Abstract
Recently, Maccone and Pati \cite{pa.1} derived new uncertainty relations which they claim to be stronger than Heisenberg-Robertson or Schrodinger uncertainty relations. Here we comment that their work is a special case of a more general uncertainty relation and we reexamine some of their conclusions.
