A superradiant maser with nitrogen-vacancy center spins [PDF]

open access: yesScience China Physics, Mechanics & Astronomy, 2021
Recent experiments have demonstrated Rabi-oscillations, superradiant pulses and stimulated emission from negatively-charged nitrogen-vacancy ($\mathrm{NV}^{-}$) center spins in microwave resonators. These phenomena witness the kind of collective and strong coupling which has been prerequisite for observation of superradiant lasing in the optical ...

Spin-Mechanics with Nitrogen-Vacancy Centers and Trapped Particles [PDF]

open access: yesMicromachines, 2021
Controlling the motion of macroscopic oscillators in the quantum regime has been the subject of intense research in recent decades. In this direction, opto-mechanical systems, where the motion of micro-objects is strongly coupled with laser light radiation pressure, have had tremendous success.

Probing NV and SiV charge state dynamics using high-voltage nanosecond pulse and photoluminescence spectral analysis

open access: yesMaterials for Quantum Technology, 2023
Nitrogen-vacancy (NV) and silicon-vacancy (SiV) color defects in diamond are promising systems for applications in quantum technology. The NV and SiV centers have multiple charge states, and their charge states have different electronic, optical and spin

Decoherence Control of Nitrogen-Vacancy Centers [PDF]

open access: yesScientific Reports, 2017
AbstractQuantum mechanical systems lose coherence through interacting with external environments—a process known as decoherence. Although decoherence is detrimental for most of the tasks in quantum information processing, a substantial degree of decoherence is crucial for boosting the efficiency of quantum processes, for example, in quantum biology and

Relaxometry with Nitrogen Vacancy (NV) Centers in Diamond

open access: yesAccounts of Chemical Research, 2022
Relaxometry is a technique which makes use of a specific crystal lattice defect in diamond, the so-called NV center. This defect consists of a nitrogen atom, which replaces a carbon atom in the diamond lattice, and an adjacent vacancy. NV centers allow converting magnetic noise into optical signals, which dramatically increases the sensitivity of the ...

Preparation and characterization of AFM tips with nitrogen-vacancy and nitrogen-vacancy-nitrogen color centers

open access: yesPhotonics Letters of Poland, 2021
We demonstrate a simple dip-coating method of covering standard AFM tips with nanodiamonds containing color centers. Such coating enables convenient visualization of AFM tips above transparent samples as well as using the tip for performing spatially resolved magnetometry. Full Text: PDF ReferencesG. Binnig, C. F.

Conversion of neutral nitrogen-vacancy centers to negatively charged nitrogen-vacancy centers through selective oxidation [PDF]

open access: yesApplied Physics Letters, 2010
The conversion of neutral nitrogen-vacancy centers to negatively charged nitrogen-vacancy centers is demonstrated for centers created by ion implantation and annealing in high-purity diamond. Conversion occurs with surface exposure to an oxygen atmosphere at 465 °C. The spectral properties of the charge-converted centers are investigated.

Amplified nanoscale detection of labeled molecules via surface electrons on diamond

open access: yesCommunications Physics, 2023
The detection of individual molecules and their dynamics is a long-standing challenge in the field of nanotechnology. In this work, we present a method that utilizes a nitrogen vacancy (NV) center and a dangling bond on the diamond surface to measure the

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

open access: yesPhysical 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]

open access: yesPhysical 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.
