A class of optimal positive maps in
arXiv:2207.03821 · doi:10.1016/j.laa.2023.03.015
Abstract
It is proven that a certain class of positive maps in the matrix algebra consists of optimal maps, i.e. maps from which one cannot subtract any completely positive map without loosing positivity. This class provides a generalization of a seminal Choi positive map in .
