Color centers in nanodiamonds (NDs) offer one promising platform for a huge variety of quantum technology applications ranging from quantum networks to quantum sensors. In this course the negatively charged nitrogen-vacancy (NV−) and silicon-vacancy (SiV−) center have been extensively studied due to their outstanding spin and optical properties.
We present nanomanipulation of NDs exhibiting single SiV− centers. In particular we demonstrate the translation and rotation of a ND with the help of an AFM cantilever and explicitly show that the optical properties are conserved. We further investigate the potential of these NDs for their integration into quantum optics and photonics devices and the optical coupling of individual SiV− centers in NDs.
