- Abstract
We investigate effects of a collective disentanglement eraser performed over states of two pairs of pre-entangled cavities tagged independently with two identical three-level atoms. It is shown that the collective disentanglement operation ensures not only the recovery of initial coherence but also its extension from the initial two to four qubits, generating four-qubit field cluster states. We also propose a cavity QED scheme to generate an arbitrary field graph state by means of a collective operation of disentanglement erasers.
