Phys. Rev. Lett. 93, 230501 (2004) [4 pages]Decoherence and Multipartite EntanglementReceived 6 July 2004; published 1 December 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. © 2004 The American Physical Society URL:
