Nitrogen-vacancy center

Simplified atomic structure of the NV center

The nitrogen-vacancy center (N-V center or NV center) is one of numerous photoluminescent point defects in diamond. Its most explored and useful properties include its spin-dependent photoluminescence (which enables measurement of the electronic spin state using optically detected magnetic resonance), and its relatively long (millisecond) spin coherence at room temperature.[1] The NV center energy levels are modified by magnetic fields,[2] electric fields,[3] temperature,[4] and strain,[5] which allow it to serve as a sensor of a variety of physical phenomena. Its atomic size and spin properties can form the basis for useful quantum sensors.[6] It has also been explored for applications in quantum computing (e.g. for entanglement generation[7]), quantum simulation,[8] and spintronics.[9]
