摘要：The dynamics of the quantum correlation between two atoms in two single-mode cavities is studied. For the initial Bell state |I (+)>, the quantum consonance is equal to the entanglement, and larger than quantum discord. For the initial Bell state |I broken vertical bar (+)>, the quantum consonance is larger than entanglement, but not larger than quantum discord all the time. As the increase of the cavity-cavity coupling strength, the evolution period of quantum correlation becomes smaller. Consonance is not smooth at some points while cavities are coupled with each other.
