Measurement-induced disturbance between two atoms in Tavis—Cummings model with dipole—dipole interaction
Guo‐Feng Zhang, Xiao Wang, Guang‐Hong Lu · Chinese Physics B · 2014
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.
