Abstract
Section titled āAbstractāThe sensing capability of a single optically bright electronic spin in\ndiamond can be enhanced by making use of proximal dark nuclei as ancillary\nspins. Such systems, so far only realized in bulk diamond, provide orders of\nmagnitude higher sensitivity and spectral resolution in the case of magnetic\nsensing, as well as improved readout fidelity and state storage time in quantum\ninformation schemes. In nanodiamonds, which offer additional opportunities as\nmobile nanoscale sensors, electronic-nuclear spin complexes have remained\ninaccessible. We demonstrate coherent control of a 13C nuclear spin located\n4{\AA} from a nitrogen-vacancy center in a nanodiamond and show quantum-state\ntransfer between the two components of this hybrid spin system. We extract a\nnuclear-spin free precession time of T2* = 26 us, which exceeds the bare\nelectron free precession time in nanodiamond by two orders of magnitude.\n
