Entanglement witnesses for a class of bipartite states of n x n qubits
Fabio Benatti, Mahya Karbalaii
We characterize the positive maps detecting the entangled bipartite states of n x n qubits that are diagonal with respect to the orthonormal basis constructed by tensor products of…

Entanglement Witnessing based on Positive Maps: Characterization of a Class of Bipartite n x n qubit Systems
Mahya Karbalaii
In this thesis work, we have studied the role of positive and completely positive maps in detecting entanglement.
