Abstract
Based on the description of ameliorated measurement-induced disturbance (AMID) and negativity, the behaviors of quantum correlation (QC) and quantum entanglement (QE) are discussed for a model of two atoms resonantly interact with a single-mode cavity simultaneously. The result shows that the QC and QE of two atoms can be transferred to those of atom-cavity subsystems during the evolution, and vice versa. Meanwhile, the AMID can reveal more properties of QC than negativity in the presented physical system. It is worth noting that the AMID can be increased evidently for the certain special chosen system parameters. In addition, Bell non-locality for this given system is analyzed and it is shown that Bell non-locality can also be transferred regularly between all bipartite states.
