We present a theoretical proposal to couple a single Nitrogen-Vacancy (NV)\ncenter to a superconducting flux qubit (FQ) in the regime where both systems\nare off resonance. The coupling between both quantum devices is achieved\nthrough the strong driving of the flux qubit by a classical microwave field\nthat creates dressed states with an experimentally controlled characteristic\nfrequency. We discuss several applications such as controlling the NV center’s\nstate by manipulation of the flux qubit, performing the NV center full\ntomography and using the NV center as a quantum memory. The effect of\ndecoherence and its consequences to the proposed applications are also\nanalyzed. Our results provide a theoretical framework describing a promising\nhybrid system for quantum information processing, which combines the advantages\nof fast manipulation and long coherence times.\n
