Multiparticle entanglement under the influence of decoherence
Multiparticle entanglement under the influence of decoherence
We present a method to determine the decay of multiparticle quantum correlations as quantified by the geometric measure of entanglement under the influence of decoherence. With this, we compare the robustness of entanglement in Greenberger-Horne-Zeilinger (GHZ), cluster, $W$, and Dicke states of four qubits and show that the Dicke state …
