Coupling a single Nitrogen-Vacancy center to a superconducting flux qubit in the far off resonance regime
We present a theoretical proposal to couple a single Nitrogen-Vacancy (NV)
center to a superconducting flux qubit (FQ) in the regime where both systems
are off resonance. The coupling between both quantum devices is achieved
through the strong driving of the flux qubit by a classical microwave field
that creates dressed states with an experimentally controlled characteristic
frequency. We discuss several applications such as controlling the NV center's
state by manipulation of the flux qubit, performing the NV center full
tomography and using the NV center as a quantum memory. The effect of
decoherence and its consequences to the proposed applications are also
analyzed. Our results provide a theoretical framework describing a promising
hybrid system for quantum information processing, which combines the advantages
of fast manipulation and long coherence times.Comment: 8 pages, 9 figure
