Popis:	The collision model of Ziman et al. was considered and the robustness of N-qubit Greenberger-Horne-Zeilinger (GHZ), W, and linear cluster states were studied. Our results show that N-qubit entanglement of GHZ states would be extremely fragile under collisional decoherence, and that of W states could be more robust than of linear cluster states.
