Terahertz emission from diamond nitrogen-vacancy centers. [PDF]

Sci Adv
Coherent light sources emitting in the terahertz range are highly sought after for fundamental research and applications. Terahertz lasers rely on achieving population inversion. We demonstrate the generation of terahertz radiation using nitrogen-vacancy centers in a diamond single crystal.

Decoherence Control of Nitrogen-Vacancy Centers. [PDF]

Sci Rep, 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

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 ...

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

Phys Rev Lett, 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.

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 ...
