A class of generalized positive linear maps on matrix algebras (1704.01288v1)
Published 5 Apr 2017 in math.OA
Abstract: We construct a class of positive linear maps on matrix algebras. We find conditions when these maps are atomic, decomposable and completely positive. We obtain a large class of atomic positive linear maps. As applications in quantum information theory, we discuss the structural physical approximation and optimality of entanglement witness associated with these maps.
