Findings

Corrected expressions for classical and quantum correlations.

Included previously omitted cases in optimization.

Improved understanding of correlation quantifiers in Bell Diagonal states.

Abstract

In this brief paper, we complete the analysis presented previously in [RMF 64 (2018) 662-670, arXiv:1803.02426] regarding the quantifiers of the classical correlations and the so-called local available quantum correlations for Bell Diagonal states. A correction is introduced in their previous expressions once two cases within the optimizations are included.
