Abstract
Section titled âAbstractâAbstract The paper investigates the dynamics of the quantum interferometric power and Local quantum uncertainty coherences beyond concurrence entanglement between two Nitrogen-Vacancy centers (NVCs) induced by two coupled dissipative nanocavities. A particular engineering design is considered, where each nanocavity contains a coherently driven N-V center and the two nanocavities are initially in a maximally correlated state with different initial two-NVC states. It is found that, for the initial uncorrelated two-NVC state, the generated two-NVC coherence and the entanglement due to the NVC-nanocavity interactions can be enhanced by the increase of the Nitrogen-Vacancy centerâs couplings. The cavity dissipations enhance the generation of Fisher and skew information quantumness of the two-NVC state, and accelerate the reduction of the concurrence entanglement. For the initial maximally correlated two-NVC state, the robustness of the two-NVC coherence and the entanglement against the NVC-nanocavity interactions and the dissipation can be enhanced by the two-nanocavity coupling and the two NVC-qubits couplings.
