Geometric Characterization and Feasible Region Analysis of Bipartite Qutrit Bound Entanglement
Mazhar Ali
We characterize bound entanglement in bipartite qutrit systems by combining the Positive Partial Transpose (PPT) criterion with a structural, non-completely positive map. Focusing…

Bound entanglement detection in systems via generalized Choi maps
Mazhar Ali
We construct a family of positive but not completely positive linear maps acting on four dimensional space. We employ these maps to detect bound entanglement in high dimensional qu…
