A protocol is proposed to implement nongeometric phase gates and generate entangled states by the adiabatic evolution of dark states in two distant cavities. The influence of various decoherence processes such as spontaneous emission and photon loss on the fidelity and success probability is also discussed. And this protocol can be generalized to generate N-atom entangled states.
