Abstract:
The influence of dipole-dipole interaction on dynamics of three- and four-particle GHZ states for two $\Delta$-type superconducting flux cubits interacting with one or two different electronic $LC$ cavities via two-photon processes has been investigated. The results show that dipole-dipole interaction does not lead to the disappearance of the effect of entanglement sudden death and does not change the maximum degree of entanglement.
Keywords:
supercoducting flux cubits, degenerate and nondegenerate two-photon transitions, entanglement of cubits, sudden death of entanglement.
