Diamond nanotechnology

Abstract:
One exciting application at the forefront of diamond research is in quantum science. Nonclassical (single-photon) light sources based on individual color centers in diamond, most notably the nitrogen-vacancy (NV) center, have been used for secure communication based on quantum-cryptography protocols. Coupling between the NV center's electronic spin and nearby nuclear spins can be used to form a large qubit register, an essential ingredient for a quantum computer.

Recently, techniques designed to manipulate the NV center have been applied to nanoscale magnetic-field sensing based on single spins. But practical implementations of these technologies require efficient excitation and extraction of single photons from NV centers using a simple optical system. This is a challenge because of the high refractive index of the diamond host, so that the majority of photons emitted from an embedded color center are not accessible even to sophisticated setups.
