Entanglement Swapping and Disentanglement via an Entangled State of Atoms Interacting with a Cavity Field
Tang-Kun Liu, Ji‐Suo Wang, Jian Feng, Mingsheng Zhan · Chinese Physics Letters · 2002
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 two other 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 an appropriate interaction time of atom C with the coherent field.
