Query: Single Silicon Vacancy Centers in 10-Nanometer Diamonds for Quantum
  Information Applications   Ultra-small, low-strain, artificially produced diamonds with an internal,
active color center have substantial potential for quantum information
processing and biomedical applications. Thus, it is of great importance to be
able to artificially produce such diamonds. Here, we report on the
high-pressure, high-temperature synthesis of such nanodiamonds about 10 nm in
size and containing an optically active, single silicon-vacancy color center.
Using special sample preparation technique, we were able to prepare samples
containing single nanodiamonds on the surface. By correlating atomic-force
microscope images and confocal optical images we verified presents of optically
active color centers in single nanocrystals, and using second-order correlation
measurements proved single-photon emission statistics of this nanodiamonds.
This color centers have non-blinking, spectrally narrow emission with narrow
distribution of spectral width and positions of zero-phonon line thus proving
high quality of the nanodiamonds produced
