Degradable Strongly Entanglement Breaking Maps

Repana Devendra, Gunjan sapra, K. Sumesh

In this paper, we provide a structure theorem and various characterizations of degradable strongly entanglement breaking maps on separable Hilbert spaces. In the finite dimensional…

-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…

On a generalization of Ando's dilation theorem

Nirupama Mallick, K. Sumesh

We introduce the notion of -commuting operators which is a generalization of commuting operators. We prove a generalized version of commutant lifting theorem and Ando's dilation…

On a tensor-analogue of the Schur product

K. Sumesh, V. S. Sunder

We consider the tensorial Schur product for with unital $C…

Bures Distance For Completely Positive Maps

B. V. Rajarama Bhat, K. Sumesh

D. Bures had defined a metric on the set of normal states on a von Neumann algebra using GNS representations of states. This notion has been extended to completely positive maps be…

CP-H-Extendable Maps between Hilbert modules and CPH-Semigroups

Michael Skeide, K. Sumesh

One may ask which maps between Hilbert modules allow for a completely positive extension to a map acting block-wise between the associated (extended) linking algebras. In these not…

Stinespring's theorem for maps on Hilbert C*-modules

B V Rajarama Bhat, G. Ramesh, K. Sumesh

We strengthen Mohammad B. Asadi's analogue of Stinespring's theorem for certain maps on Hilbert C*-modules. We also show that any two minimal Stinespring representations are unitar…
