Idea

In solid state physics, an impure form of diamond may be obtained where, in the center of the Bravais lattice, carbon nuclei are replaced by a nitrogen nucleus and a vacancy, referred to as the nitrogen-vacancy center in diamond (often short: NV center).

In such a material, the spin of one of the electron orbitals bound to the nitrogen nucleus has a long quantum decoherence time and lends itself to manipulation by spin resonance.

Therefore NV center spins serve as a platform for spin resonance qbits, used in quantum sensing, quantum information processing and simple quantum computing.
