Robust atomic entanglement in two coupled cavities via virtual excitations and quantum Zeno dynamics

Robust atomic entanglement in two coupled cavities via virtual excitations and quantum Zeno dynamics A novel proposal for the robust generation of atomic entanglement in two coupled cavities is proposed, for the first time via virtually excitation and quantum Zeno dynamics. Throughout the procedure, both cavity modes and atoms are only virtually excited, making the system robust against atomic and photonic decays. The influence of the atom-photon decay and the imperfection of the initial atom state on the prepared-state fidelity is also analyzed, which shows that the present scheme is feasible based on current technologies. At last, the proposal is generalized for the preparation of two atomic ensembles. Quantum Information Processing Springer Journals
