Abstract
Section titled “Abstract”We investigate the dynamics of quantum coherence among multiple diamond nitrogen-vacancy centers (NVCs) coupled to a microsphere whispering-gallery-mode (WGM) cavity under external driving, through numerically simulating the Markovian quantum master equation. We show that quantum coherence (both normal quantum coherence and relative entropy) displays a series of damped oscillations under various experimental situations, which reflects the intricate interplay and competition between the dissipative effects and NVC-WGM coupling. Our results also show that normal quantum coherence is an upper bound for relative entropy. The feasibility of our proposal is supported by currently available experimental techniques.
