文摘

We propose a one-step scheme for creating entanglement between two distant nitrogen-vacancy (NV) centers, which are placed in separate single-mode nanocavities in a planar photonic crystal (PC). With a laser-driven, the decoherence from the excited states of the NV centers can be effectively suppressed by virtue of the Raman transition in the dispersive regime. With the assistant of a strong classical field, fast operation can be achieved. The experimental feasibility of the scheme is discussed based on currently available technology.
