Charged dopants in neutral supercells through substitutional donor (acceptor): nitrogen donor charging of the nitrogen-vacancy center in diamond

New insight into the spin-conserving excitation of the negatively charged nitrogen-vacancy center in diamond

The negatively charged nitrogen-vacancy (N-V(-)) color center in diamond is an important solid-state single photon source for applications to quantum communication and distributed quantum computation. Its full usefulness relies on sufficient radiative emission of the optical photons which requires realizable control to enhance emission into the zero-phonon line (ZPL) but until now is still a ch...

Single-Qubit Operations with the Nitrogen-Vacancy Center in Diamond

A concept combining optics and microwave pulses with the negative charge-state of the nitrogenvacancy (NV– ) center in diamond is demonstrated through experiments that are equivalent to single-qubit gates, and decoherence for this qubit is examined. The spin levels of the ground state provide the two-level system. Optical excitation provides polarization of these states. The polarized state is ...

Zinc-Vacancy–Donor Complex: A Crucial Compensating Acceptor in ZnO

Temperature dependence of the nitrogen-vacancy magnetic resonance in diamond.

The temperature dependence of the magnetic-resonance spectra of nitrogen-vacancy (NV-) ensembles in the range of 280-330 K was studied. Four samples prepared under different conditions were analyzed with NV- concentrations ranging from 10 ppb to 15 ppm. For all samples, the axial zero-field splitting (ZFS) parameter D was found to vary significantly with temperature, T, as dD/dT=-74.2(7) kHz/K....
