-extreme points of entanglement breaking maps
B. V. Rajarama Bhat, Repana Devendra, Nirupama Mallick +1
In this paper we study the -convex set of unital entanglement breaking (EB-)maps on matrix algebras. General properties and an abstract characterization of -extreme point…
Mapping cone of -Entanglement Breaking Maps
Repana Devendra, Nirupama Mallick, K. Sumesh
In \cite{CMW19}, the authors introduced -entanglement breaking linear maps to understand the entanglement breaking property of completely positive maps on taking composition. In…
Roots of Completely Positive Maps
B. V. Rajarama Bhat, Robin Hillier, Nirupama Mallick +1
We introduce the concept of completely positive roots of completely positive maps on operator algebras. We do this in different forms: as asymptotic roots, proper discrete roots an…
Nilpotent Completely Positive Maps
B V Rajarama Bhat, Nirupama Mallick
We study the structure of nilpotent completely positive maps in terms of Choi-Kraus coefficients. We prove several inequalities, including certain majorization type inequalities fo…
