摘要： Quantum correlation, measured by measurement-induced disturbance (MID), between two two-level atoms is investigated in detail in Tavis-Cummings model with dipole-dipole interaction (DDI). We find that MID can be determined only by the dipole-dipole interaction between the two atoms when the cavity and atoms are at resonance. Moreover, DDI will have different effects on MID for two different kinds of initial states.
