"coherence times" refers to the amount of time that something remains stable, consistent, or connected before changes occur that disrupt its harmony or clarity. Full definition
We combine these techniques to detect nuclear magnetic resonance from dilute 31P in the purest available sample of 28Si, at concentrations inaccessible to conventional measurements, measuring a solid - state coherence time of over 180 seconds. (science.sciencemag.org)
Nitrogen Vacancy (NV) color centers exhibit remarkable and unique properties, including long coherence times at room temperature (~ ms), optical initialization and readout, and coherent microwave control. (sciencedaily.com)
This is because holes have reduced hyperfine coupling to nuclear spins, allowing long spin coherence times [1], while the enhanced spin - orbit coupling of holes enables fast all - electric spin manipulation via EDSR [2]. (cqc2t.org)
