Defects in diamond : a new tool for quantum technologies ?

Vincent JACQUES, Laboratoire de Photonique Quantique et Moléculaire, ENS de Cachan

Among many studied optically-active defects in diamond, the negatively-charged Nitrogen-Vacancy (NV) color center has attracted a lot of interest during the past years owing to its unprecedented optical and spin properties at room temperature. The NV defect electron spin can be initialized, coherently manipulated with long coherence time and read-out by pure optical means through its perfectly photostable spin-dependent photoluminescence. Such properties are the cornerstone of a wide range of emerging technologies, from imaging in life science, to quantum information processing and high resolution sensing of magnetic fields.

In this talk, I will discuss recent experiments using NV defect in diamond for nanoscale magnetometry and hybrid quantum systems.
