Abstract We consider entanglement swapping and disentanglement schemes via an entangled state of three two-level atoms interacting with a coherent field. When a two-level atom C, entangled with other two two-level atoms A and B, is injected into a high-Q cavity and atoms A and B are far away from the cavity, the entanglement swapping or disentanglement can be realized by carrying out the measurement on the atom C and by selecting appropriate interaction time of atom C with the coherent field.
