Physical Review Materials, 2023 In diamond, nitrogen defects like the substitutional nitrogen defect (Ns) or the nitrogen-vacancy-hydrogen complex (NVH) outnumber the nitrogen-vacancy (NV) defect by at least one order of magnitude creating a dense spin bath. While neutral Ns has an impact on the coherence of the NV spin state, the atomic structure of NVH reminds of a NV center ...

Decoherence Control of Nitrogen-Vacancy Centers [PDF]
Scientific 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

Imaging the Local Charge Environment of Nitrogen-Vacancy Centers in Diamond
Physical Review Letters, 2018 Characterizing the local internal environment surrounding solid-state spin defects is crucial to harnessing them as nanoscale sensors of external fields. This is especially germane to the case of defect ensembles which can exhibit a complex interplay between interactions, internal fields and lattice strain. Working with the nitrogen-vacancy (NV) center

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

Relaxometry with Nitrogen Vacancy (NV) Centers in Diamond
Accounts 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 ...
