Multiqubits Entanglement Based on Optimal Witness
arXiv:0906.1507 · doi:10.1016/S0034-4877(09)90012-X
Abstract
We study the optimal entanglement witness with respect to multiqubits W-states. We show such entanglement witnesses can be used to distinguish genuine entangled states, different biseparable states and fully separable states.
