  Quantum entanglement is important quanum resources in quantum information
sicence. Here we propose an approach to {preparing} atomic quantum entanglement
in a hybrid atom-cavity-fiber system. Using quantum Zeno dynamics method, the
system evolution states are always split into a series of Zeno invariant
{subspaces} consisting of dark and bright states. By choosing the initial state
of the system, the bright states are all neglected and only dark states are
kept to build the effective Hamiltonian. By tuning the system parameters,
two-atom multiple-dimensional entanglement, two-atom Bell state, and three-atom
GHZ state can be realized by one step. Our proposal provides a way to perform
quantum information processing with dark states.
