    "abstract": "We consider the collision model of Ziman {\\em et al.} and study the\nrobustness of $N$-qubit Greenberger-Horne-Zeilinger (GHZ), W, and linear\ncluster states. Our results show that $N$-qubit entanglement of GHZ states\nwould be extremely fragile under collisional decoherence, and that of W states\ncould be more robust than of linear cluster states. We indicate that the\ncollision model of Ziman {\\em et al.} could provide a physical mechanism to\nsome known results in this area of investigations. More importantly, we show\nthat it could give a clue as to how $N$-partite distillable entanglement would\nbe relatively rare in our macroscopic classical world.",
