TL;DR: An improvement of more than two orders of magnitude is demonstrated in the spin coherence time of nitrogen-vacancy centres of diamond, which could advance quantum sensing, enable squeezing and many-body entanglement, and open a path to simulating driven, interaction-dominated quantum many- body Hamiltonians.

TL;DR: An experimental study of the longitudinal electron-spin relaxation time (T1) of negatively charged nitrogen-vacancy ensembles in diamond as a function of temperature and magnetic field reveals three processes responsible for T1 relaxation.

TL;DR: In this article, the optical properties of the 1042 nm transition of negatively charged nitrogen-vacancy (NV) centers in type-1b diamond have been investigated and the results indicate that the upper level of this transition couples to the ${m}_{s}=\ifmmode\pm\else\textpm\fi{}1$ sublevels of the $^{3}E$ excited state and is short lived with a lifetime of

TL;DR: This work reports on an alternative principle for detecting the magnetic resonance of nitrogen-vacancy centres, allowing the direct photoelectric readout ofnitrogen-v Vacancy centres spin state in an all-diamond device.

TL;DR: In this article, the spin state of high-density nitrogen-vacancy ensembles in diamond using optical absorption at 1042 nm was detected by detecting the spin states of high density nitrogen vacancy in diamond.
