Abstract

 

We theoretically demonstrate how to achieve quantum entanglement control of a dissipative anisotropic
two-qubit Heisenberg XYZ model. New dynamical features of local quantum coherence, local quantum
Fisher information and Bures distance entanglement are achieved by controlling the initial state setting,
DM interaction and decoherence. The proposed scheme allows for the generation of sudden changes in the
entanglement. We illustrate the control by manipulating the local quantum coherence, Fisher information
dynamics, and the sudden appearance of the disentanglement intervals. We further consider simultaneous
changes in these behaviors for different values of the system parameters. These results provide helpful
significance for understanding the dynamics of the dissipative anisotropic two-qubit Heisenberg XYZ model.
