Revealing the Emergence of Classicality Using Nitrogen-Vacancy Centers [PDF]

Physical Review Letters, 2019
The origin of classical reality in our quantum world is a long-standing mystery. Here, we examine a nitrogen vacancy center evolving naturally in the presence of its environment to study quantum Darwinism - the proliferation of information about preferred quantum states throughout the world via the environment.

Mechanical Spin Control of Nitrogen-Vacancy Centers in Diamond [PDF]

Physical Review Letters, 2013
As spin-based quantum technology evolves, the ability to manipulate spin with non-magnetic fields is critical - both for the development of hybrid quantum systems and for compatibility with conventional technology. Particularly useful examples are electric fields, optical fields, and mechanical lattice vibrations.

Coherent Optical Transitions in Implanted Nitrogen Vacancy Centers [PDF]

Nano Letters, 2014
We report the observation of stable optical transitions in nitrogen-vacancy (NV) centers created by ion implantation. Using a combination of high temperature annealing and subsequent surface treatment, we reproducibly create NV centers with zero-phonon lines (ZPL) exhibiting spectral diffusion that is close to the lifetime-limited optical line width ...

Optomechanical Quantum Control of a Nitrogen Vacancy Center in Diamond [PDF]

Conference on Lasers and Electro-Optics, 2016
We demonstrate optomechanical quantum control of the internal electronic states of a diamond nitrogen vacancy (NV) center in the resolved-sideband regime by coupling the NV to both optical fields and surface acoustic waves via a phonon-assisted optical transition and by taking advantage of the strong excited-state electron-phonon coupling of a NV ...

Nitrogen-vacancy color centers created by proton implantation in a diamond [PDF]

, 2021
We present an experimental study of the longitudinal and transverse relaxation of ensembles of negatively charged nitrogen-vacancy (NV−) centers in a diamond monocrystal prepared by 1.8 MeV proton implantation.

Nanoscale Vacancy-Mediated Aggregation, Dissociation, and Splitting of Nitrogen Centers in Natural Diamond Excited by Visible-Range Femtosecond Laser Pulses

Nanomaterials, 2023
Natural IaA+B diamonds were exposed in their bulk by multiple 0.3 ps, 515 nm laser pulses focused by a 0.25 NA micro-objective, producing in the prefocal region (depth of 20–50 μm) a bulk array of photoluminescent nanostructured microtracks at variable ...

Optimization of the coherence properties of diamond samples with an intermediate concentration of NV centers

Results in Physics, 2021
The sensitivity of the nitrogen-vacancy (NV) color centers in diamond-based magnetometers strongly depends on the number of NV centers involved in the measurement.

Optically Coherent Nitrogen-Vacancy Defect Centers in Diamond Nanostructures

Physical Review X, 2023
Optically active solid-state spin defects have the potential to become a versatile resource for quantum information processing applications. Nitrogen-vacancy defect centers (NV) in diamond act as quantum memories and can be interfaced with coherent ...

Low-loss broadband antenna for efficient photon collection from a coherent spin in diamond [PDF]

, 2014
We report the creation of a low-loss broadband optical antenna giving highly directed output from a coherent single spin in the solid state. The device, a crystalline solid-state realization of a dielectric antenna, is engineered for individual nitrogen ...
