Novel quantum applications of color centers in diamond
A nitrogen-vacancy color center (NV center) in diamond possesses a lot of interesting and useful features. Consisting of a nitrogen substitute of a carbon atom and a nearby vacancy, a NV center traps an extra electron and behaves as an effective artificial atom. One of the most fascinating characteristics of it is that a NV center can be coherently manipulated, just like a trapped ultra cold atom, for long enough time, but now even at room temperature! We explore the potential applications of this quantum object in various contexts ranging from magnetometry to NMR imaging or to a novel experimental platform of studying many-body quantum dynamics.
