Comments on "Stronger Uncertainty Relations for All Incompatible Observables"

TL;DR

This paper critiques recent claims of stronger uncertainty relations by showing they are special cases of a more general relation and reexamines some of their conclusions.

Contribution

It demonstrates that Maccone and Pati's uncertainty relations are specific instances of a broader framework and provides a critical analysis of their claims.

Findings

Maccone and Pati's relations are special cases of a more general uncertainty relation

Reevaluation of some conclusions drawn by Maccone and Pati

Clarification of the scope of stronger uncertainty relations

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.
