We investigate the non-Markovian dynamics of quantum correlation between two initially
entangled nitrogen-vacancy centers (NVCs) embedded in photonic-crystal cavities (PCCs).
We find that a finite quantum correlation is preserved even asymptotically when the
transition frequency of the NVC is within the band gap of the PCC, which is quantitatively
different from the result of approaching zero under the Born-Markovian approximation. In
addition, once the transition frequency of NVC is far beyond the band gap of the PCC, the …

We investigate the dynamics of quantum correlation between two separated nitrogen
vacancy centers (NVCs) placed near a one-dimensional plasmonic waveguide. As a
common medium of the radiation field of NVCs propagating, the plasmonic waveguide can
dynamically induce quantum correlation between the two NVCs. It is interesting to find that
such dynamically induced quantum correlation can be preserved in the long-time steady
state by locally applying individual driving on the two NVCs. In particular, we also show that …
