A complete characterization of eventually entanglement breaking unital quantum channels
B. V. Rajarama Bhat, Pankaj Dey, Biswarup Saha
We obtain a complete characterization of eventually entanglement breaking (EEB) unital channels in terms of some simple commutation properties of their eigenvectors. Specifically,…

Spectral radii for subsets of Hilbert -modules and spectral properties of positive maps
B. V. Rajarama Bhat, Biswarup Saha, Prajakta Sahasrabuddhe
The notions of joint and outer spectral radii are extended to the setting of Hilbert -bimodules. A Rota-Strang type characterisation is proved for the joint spectral radius. I…
