Abstract: | The two atoms in the ion trap are entangled by the interaction
with an external excited atom. The evolution of the entanglement
is analytically derived without the decoherence. Considering the
spontaneous decay from the environment, the evolution of the
entanglement is similar to the damping Rabi oscillation. The
generation of entanglement is induced by the dipole-dipole type
interaction of atoms. It is found that the entanglement of two
trapped atoms is robust with the uniform interaction with the
external atom. The collective spontaneous emission from the
coupling between the atoms may enhance the entanglement. |
