In this paper, we study the dynamics of atom–atom entanglement inside a single-mode cavity using quantum Zeno dynamics (QZD). The system under study consists of two two-level atoms with dipole–dipole and Ising interactions. By applying QZD, based on strong continuous coupling, we study the possibility of generating atom–atom entanglement in terms of different initial states. Furthermore, we control the dynamics of atom–atom entanglement in different quantum Zeno regimes. To show its efficiency, we compare the entanglement dynamics under QZD to free evolution. We show that in comparison with free evolution of a system, QZD not only does restrict the dynamics in the subspace where the system is initially prepared, but also preserves entanglement.
