Abstract: We position a single nitrogen-vacancy (NV) centre hosted in a diamond nanocrystal at the extremity of a SiC nanowire. <–more!><\/p>\n
This novel hybrid system couples the degrees of freedom of two radically different systems: a nanomechanical oscillator and a
\nsingle quantum object. We probe the dynamics of the nano-resonator through time-resolved nanocrystal fluorescence and photon-correlation measurements, conveying the influence of a mechanical degree of freedom on a non-classical photon
\nemitter. Moreover, by immersing the system in a strong magnetic field gradient, we induce a magnetic coupling between
\nthe nanomechanical oscillator and the NV electronic spin, providing nanomotion readout through a single electronic spin.
\nSpin-dependent forces inherent to this coupling scheme are essential in a variety of active cooling and entanglement protocols
\nused in atomic physics, and should now be within the reach of nanomechanical hybrid systems.<\/p>\n
