Quantum sensing with single spins in diamond

Vincent Jacques
ENS Cachan, France

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 nanoscale magnetometry.
In this talk, I will present recent experiments where single spins in diamond are used either as solid-state qubits or as highly sensitive magnetic field sensors.
