Abstract
Section titled āAbstractāWe demonstrate the three-dimensional localization of a single nitrogen-vacancy (NV) center in nanodiamond by the use of position-dependent standing-wave laser fields in an external magnetic field. We show that various localization phenomena including cask-like, disc-like, cylinder-like, and sphere-like patterns can be achieved by monitoring the probe absorption spectrum in two different coupling formalisms. By selecting an appropriate combination of system parameters, we can localize an individual NV center within a subspace at a deterministic position, which is a consequence of quantum interference. Furthermore, this deterministic positional control of coherent NV centers may have potential applications in NV-based nanostructures, such as sensing and quantum information-processing devices.
