Electric-Field-Induced Coherent Control of Nitrogen-Vacancy Centers

Physical Review Applied, 2022
Enabling scalable and energy-efficient control of spin defects in solid-state media is desirable for realizing transformative quantum information technologies. Exploiting voltage-controlled magnetic anisotropy, we report coherent manipulation of nitrogen-vacancy (NV) centers by the spatially confined magnetic stray fields produced by a proximate ...

Two-beam coupling by nitrogen-vacancy centers in diamond [PDF]

Optics Letters, 1992
A new method for two-beam coupling measurements based on acousto-optic modulation with subhertz tuning capability is applied to study excited-state dynamics of the nitrogen-vacancy center in diamond. Results yield fundamental decay constants and the nonlinear refractive index and are in good agreement with the calculated dual grating response to ...

Zero- and Low-Field Sensing with Nitrogen-Vacancy Centers

Physical Review Applied, 2022
Over the years, an enormous effort has been made to establish nitrogen vacancy (NV) centers in diamond as easily accessible and precise magnetic field sensors. However, most of their sensing protocols rely on the application of bias magnetic fields, preventing their usage in zero- or low-field experiments.

Detecting nitrogen-vacancy-hydrogen centers on the nanoscale using nitrogen-vacancy centers in diamond

Physical Review Materials
In diamond, nitrogen defects like the substitutional nitrogen defect (Ns) or the nitrogen-vacancy-hydrogen complex (NVH) outnumber the nitrogen-vacancy (NV) defect by at least one order of magnitude creating a dense spin bath. While neutral Ns has an impact on the coherence of the NV spin state, the atomic structure of NVH reminds of a NV center ...

Gyroscopes based on nitrogen-vacancy centers in diamond

, 2012
We propose solid-state gyroscopes based on ensembles of negatively charged nitrogen-vacancy (${\rm NV^-}$) centers in diamond. In one scheme, rotation of the nitrogen-vacancy symmetry axis will induce Berry phase shifts in the ${\rm NV^{-}}$ electronic ...
