On PPT Square Conjecture
arXiv:2108.01588
Abstract
An analysis of the PPT square conjecture based on the characteristics of positive mappings given in [9] will be carried out. First, a general strategy for analyzing the PPT conjecture will be presented. Then, a detailed analysis of the certain tensor cones and their corresponding classes of mappings will be given. Special emphasis will be put on key mappings used in quantum information.
This version has undergone significant revisions, including correcting wrong statements given in Section 4
