Abstract
Section titled āAbstractāMuch attention has been paid to the nitrogen-vacancy ($N\phantom{\rule{0}{0ex}}V$) center in diamond as a promising emitter for applications in quantum information science and photonics, but so far even the best quantum emitters in nanodiamonds have suffered from spectral diffusion and broad zero-phonon lines. The authors show that $s\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}l\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}c\phantom{\rule{0}{0ex}}o\phantom{\rule{0}{0ex}}n-v\phantom{\rule{0}{0ex}}a\phantom{\rule{0}{0ex}}c\phantom{\rule{0}{0ex}}a\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}c\phantom{\rule{0}{0ex}}y$ ($S\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}V$) defects in diamond exhibit a nearly lifetime-limited linewidth, do not suffer from blinking, and are optically stable even above saturation. These results point the way to progress in $e.g.$ hybrid quantum photonics and quantum sensing.
