TL;DR
This paper investigates optimal entanglement witnesses tailored for multiqubit W-states, enabling the differentiation of genuine entanglement from biseparable and fully separable states.
Contribution
It introduces a method to construct optimal entanglement witnesses specific to multiqubit W-states, enhancing the detection and classification of quantum entanglement.
Findings
Optimal witnesses distinguish genuine multiqubit entanglement.
Witnesses differentiate biseparable and fully separable states.
Method improves entanglement detection accuracy.
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.
