Decoherence and Multipartite Entanglement
Andre R. R. Carvalho, Florian Mintert, Andreas Buchleitner · Physical Review Letters · 2004
We study the dynamics of multipartite entanglement under the influence of decoherence. A suitable generalization of concurrence reveals distinct scaling of the entanglement decay rate of Greenberger-Horne-Zeilinger and W states, for various environments.
