We propose an efficient scheme for the realization of quantum information transfer and entanglement with nitrogen-vacancy (N-V) centers coupled to a high-Q whispering-gallery mode (WGM) microresonator. We show that based on the effective dipole-dipole interaction between the N-V centers mediated by the WGM, quantum information can be transferred between the N-V centers through Raman transitions combined with laser fields. This protocol may open up promising possibilities for quantum communications with the solid-state quantum electrodynamic cavity system.
