Description
Summary:The detection of a single nitrogen-vacancy center in diamond has attracted much interest, since it is expected to lead to innovative applications in various domains of quantum information, including quantum metrology, information processing and communications, as well as in various nanotechnologies, such as biological and subdiffraction limit imaging, and tests of entanglement in quantum mechanics. We propose a novel scheme of a single NV center coupled with a multi-mode superconducting microwave cavity driven by coherent fields in squeezed vacuum. We numerically investigate the spectra in-phase quadrature and out-of-phase quadrature for different driving regimes with or without detunings. It shows that the maximum squeezing can be obtained for optimal Rabi fields. Moreover, with the same parameters, the maximum squeezing is greatly increased when the detunings are nonzero compared to the resonance case. •The detection of a single nitrogen-vacancy center in diamond is expected to lead to innovative applications in various domains.•A single NV center coupled with a multi-mode superconducting microwave cavity in squeezed vacuum is proposed.•Numerically investigation of the spectra in-phase quadrature and out-of-phase quadrature are considered.•The maximum squeezing can be obtained for optimal Rabi fields.
