An explicit formula for the polynomial entanglement measures of degree 2 of even-N qubits mixed states
M. A. Jafarizadeh, M. Yahyavi, A. Heshmati +4
Characterization of the multipartite mixed state entanglement is still a challenging problem. Since due to the fact that the entanglement for the mixed states, in general, is defin…
Nonlinear entanglement witnesses for four qubits in mutually unbiased bases
K. Aghayar, A. Heshmati, M. A. Jafarizadeh
Entanglement witness is a Hermitian operator that is useful for detecting the genuine multipartite entanglement of mixed states. Nonlinear entanglement witnesses have the advantage…
Nonlinear and linear entanglement witnesses for bipartite systems via exact convex optimization
M. A. Jafarizadeh, A. Heshmati, K. Aghayara
Linear and nonlinear entanglement witnesses for a given bipartite quantum systems are constructed. Using single particle feasible region, a way of constructing effective entangleme…
A general algorithm for manipulating non-linear and linear entanglement witnesses by using exact convex optimization
M. A. Jafarizadeh, K. Aghayar, A. Heshmati
A generic algorithm is developed to reduce the problem of obtaining linear and nonlinear entanglement witnesses of a given quantum system, to convex optimization problem. This appr…
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…
Detecting three-qubit bound MUB diagonal entangled states via Nonlinear optimal entanglement witnesses
M. A. Jafarizadeh, M. Mahdian, A. Heshmati +1
One of the important approaches to detect quantum entanglement is using linear entanglement witnesses EWs. In this paper, by determining the envelope of the boundary hyper-planes d…
