We propose a scheme for preparation of large-scale entangled W states based on
the fusion mechanism via quantum Zeno dynamics. By sending two atoms belonging to
an n-atom W state and an m-atom W state, respectively, into a vacuum cavity (or
two separate cavities), we may obtain a (n?+?m?-?2)-atom W state via detecting
the two-atom state after interaction. The present scheme is robust against both
spontaneous emission of atoms and decay of cavity, and the feasibility analysis
indicates that it can also be realized in experiment.
