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…

Sudden change of genuine multipartite entanglement in non-Markovian dynamics
Mazhar Ali
We investigate entanglement dynamics of bipartite as well multipartite systems beyond Markov approximation. We study two pairs of cavity-reservoir systems, modeled as four qubits a…

Detection of entanglement via moments of positive maps
Mazhar Ali
We have reexamined the moments of positive maps and the criterion based on these moments to detect entanglement. For two qubits, we observed that reduction map is equivalent to par…
