Manipulating NV centers with Optomechanical Crystals

CLEO: 2013, 2013
Nanophotonic optomechanical devices allow efficient control of localized, high quality factor, nanoscale mechanical resonances. By optically actuating these resonances, the properties of embedded diamond nitrogen vacancy centers can be modulated with far off resonance photons.

CATHODOLUMINESCENCE AND PHOTOLUMINESCENCE OF NV CENTERS

International Journal of Nanoscience, 2012
Nitrogen-vacancy (NV) centers in diamond are a promising candidate as a solid state qubit memory for quantum information as they possess very long coherence times even at room temperature. Furthermore, NV centers are very sensitive to their electromagnetic environment and are addressable in the GHz frequency range.

Quantum networks based on diamond NV centers

Quantum Computing, Communication, and Simulation, 2021
Quantum networks are poised to enable large-scale secure communication, distributed quantum computing and simulation by means of shared entangled states over the nodes of the network. The Nitrogen-Vacancy (NV) centre in diamond is a promising candidate to act as node of such a quantum network, with long-lived multiple qubits and an optical interface ...

A Telecom Infrastructure Compatible Quantum Link Using NV-centers

Optica Quantum 2.0 Conference and Exhibition, 2023
We show the latest progress towards establishing a solid-state, metropolitan quantum link, consisting of two remote Nitrogen Vacancy (NV)-centers and a central measurement station. The entanglement is generated by converting single emitted photons to the same frequency in the telecom L-band, guiding them to a central beamsplitter, where a joint Bell ...

Saturation spectroscopy of NV− centers in diamond

Laser Congress 2018 (ASSL), 2018
We report saturation of NV− centers resulting in ~40% inversion level under 632nm pumping. Δk/ko kinetics revealed long recovery time of NV− centers after photoionization under 532nm pump, which involved different relaxation channels depending on the probe beam wavelengths.

A Study of Optically Levitated NV Centers

The Rochester Conferences on Coherence and Quantum Optics and the Quantum Information and Measurement meeting, 2013
We present nitrogen vacancy photoluminescence measurements from a nanodiamond levitated in a free-space optical-dipole trap. Photoluminescence decreases as trap laser power increases, and modulating the trap laser results in changes in the defect charge state.

NV centers in diamond: Quantum-chemical modeling

Bulletin of the Russian Academy of Sciences: Physics, 2012
Quantum-chemical modeling is used to study the relationship between the spin states of nitrogen vacancy (NV) centers and their position on a (100) surface or in the bulk of a diamond crystal. The spin density of the NV centers is computed, and the position of the centers on the crystal surface is demonstrated to be energetically more favorable.

Secondary Radiation in Microdiamonds with NV Centers

Crystallography Reports, 2020
The regularities in the secondary radiation (fluorescence and Raman) spectra of single diamond microcrystals have been investigated. The Raman spectrum excited by infrared laser radiation exhibits the fundamental diamond mode with a frequency of 1332 cm–1 and a two-phonon band peaking at a frequency of 2615 cm–1.
