Entanglement Witnesses and Characterizing Entanglement Properties of Some PPT States
M. A. Jafarizadeh, N. Behzadi, Y. Akbari
On the basis of linear programming, new sets of entanglement witnesses (EWs) for 3x3 and 4x4 systems are constructed. In both cases, the constructed EWs correspond to the hyperplan…
Two-qutrit Entanglement Witnesses and Gell-Mann Matrices
M. A. Jafarizadeh, Y. Akbari, N. Behzadi
The Gell-Mann matrices for Lie algebra su(3) are the natural basis for the Hilbert space of Hermitian operators acting on the states of a three-level system(qutrit). So the con…
Investigating a Class of Chessboard Density Matrices via Linear and Non-linear Entanglement Witnesses Constructed by Exact Convex Optimization
M. A. Jafarizadeh, Y. Akbari, K. Aghayar +2
Here we consider a class of chessboard density matrices starting with three-qubit ones which have positive partial transposes with respect to all subsystems. T…
Multi-qubit stabilizer and cluster entanglement witnesses
M. A. Jafarizadeh, G. Najarbashi, Y. Akbari +1
One of the problems concerning entanglement witnesses (EWs) is the construction of them by a given set of operators. Here several multi-qubit EWs called stabilizer EWs are construc…
