On an inequality of Lin, Kim and Hsieh and Strong Subadditivity
arXiv:2402.15920
Abstract
We give an elementary proof of an inequality of Lin, Kim and Hsieh that implies strong subadditivity of the non Neumann entropy.
arXiv commentThis version corrects several typos, includes a short discussion of cases of equality, and corrects a small flaw in the original proof of the main lemma
