Geometrical structure of entangled states and secant variety
Hoshang Heydari
We show that the secant variety of the Segre variety gives useful information about the geometrical structure of an arbitrary multipartite quantum system. In particular, we investi…
Concurrence for multipartite states
Hoshang Heydari
We construct a generalized concurrence for general multipartite states based on local W-class and GHZ-class operators. We explicitly construct the corresponding concurrence for thr…
General pure multipartite entangled states and the Segre variety
Hoshang Heydari
In this paper, we construct a measure of entanglement by generalizing the quadric polynomial of the Segre variety for general multipartite states. We give explicit expressions for…
Quantum Violation: Beyond Clauser-Horne-Shimony-Holt Inequality
Hoshang Heydari
The best upper bound for the violation of the Clauser-Horne-Shimony-Holt (CHSH) inequality was first derived by Tsirelson. For increasing number of valued observables on bo…
Generating set for general multipartite entangled states
Hoshang Heydari
We propose a entanglement generating set for a general multipartite state based on the of concurrence. In particular, we show that concurrence for general multipartite states can b…
Quantum entanglement measure based on wedge product
Hoshang Heydari
We construct an entanglement measure that coincides with the generalized concurrence for a general pure bipartite state based on wedge product. Moreover, we construct an entangleme…
