Pure UCP Maps on Finite Toeplitz Systems and Quantum Gromov--Hausdorff Convergence
Ritul Duhan, Abhay Jindal
We study pure unital completely positive maps on the finite Toeplitz operator system of Toeplitz matrices. Our first main result gives an explicit characteriz…

Gromov-Hausdorff convergence of metric spaces of UCP maps
Tirthankar Bhattacharyya, Ritul Duhan, Chandan Pradhan
It is shown that van Suijlekom's technique of imposing a set of conditions on operator system spectral triples ensures Gromov-Hausdorff convergence of sequences of sets of unital c…
