Comment on "Uncertainty relations in terms of the Tsallis entropy
Abstract
We prove that the inequality used recently by Wilk and Wodarczyk [Phys. Rev. A 79, 062108 (2009)] to find a better lower bound in the uncertainty relations for the R\'enyi entropies is invalid. Thus, the problem of improving the bound given in our paper [Phys. Rev. A 74, 052101 (2006)] remains unsolved.
