TL;DR: The nitrogen-vacancy (NV) colour centre in diamond is an important physical system for emergent quantum technologies, including quantum metrology, information processing and communications, as well as for various nanotechnologies such as biological and sub-diffraction limit imaging, and for tests of entanglement in quantum mechanics as mentioned in this paper.

TL;DR: In this paper, point defects in diamond known as nitrogen-vacancy centres have been shown to be sensitive to minute magnetic fields, even at room temperature, and a demonstration that the spin associated with these defect centres is also sensitive to electric fields holds out the prospect of a sensor that can resolve single spins and single elementary charges at the nanoscale.

TL;DR: The results open the possibility of diamond lasers based on NV− centres, tuneable over the phonon sideband, which broadens the applications of NV− magnetometers from single centre nanoscale sensors to a new generation of ultra-precise ensemble laser sensors, which exploit the contrast and signal amplification of a lasing system.

TL;DR: The optical and spin resonances of the NV- center are observed under hydrostatic pressures up to 60 GPa and motivate powerful new techniques to measure pressure and image high-pressure magnetic and electric phenomena.
