Query: Fabrication of $^{15}\textrm{NV}^{-}$ centers in diamond using a
  deterministic single ion implanter   Nitrogen Vacancy (NV) centers in diamond are a platform for several important
quantum technologies, including sensing, communication and elementary quantum
processors. In this letter we demonstrate the creation of NV centers by
implantation using a deterministic single ion source. For this we
sympathetically laser-cool single $^{15}\textrm{N}_2^+$ molecular ions in a
Paul trap and extract them at an energy of 5.9\,keV. Subsequently the ions are
focused with a lateral resolution of 121(35)\,nm and are implanted into a
diamond substrate without any spatial filtering by apertures or masks. After
high-temperature annealing, we detect the NV centers in a confocal microscope
and determine a conversion efficiency of about 0.6\,$\%$. The
$^{15}\textrm{NV}$ centers are characterized by optically detected magnetic
resonance (ODMR) on the hyperfine transition and coherence time.
