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.

Memory-based Quantum Repeaters with NV Centers

CLEO: 2014, 2014
We present a simple design of a quantum repeater design build from single NV- centers embedded in an optical cavity. We compare different quantum networks from a simple linear chain to a fully fault-tolerant quantum internet.

Quantum voting via NV centers in diamond

2010
We describe a scheme for quantum anonymous voting of n participants based on the single nitrogen-vacancy centers in diamond. The scheme requires a bipartite entanglement creation between the electronic spins of the two distant NV centers, unitary operation of NV electronic spin together with n nearby nuclear spins of carbon isotopes, and one projective

Quantum sensing with solid state color center : NV center and VB center

Solid-state defects have been promising quantum sensors for detecting physical quantities such as magnetic and electric fields, pressure, and temperature. The NV center has been a standout candidate since its first discovery in 1997. Techniques such as Optically Detected Magnetic Resonance (ODMR), Hahn echo measurements, and dynamical decoupling have ...
