Abstract: | We propose a scheme of entanglement transfer through two independent arrays of cavities coupled by optical fibers when each
of the cavities contains a single two-level atom. We study the entanglement dynamics of the transferred states and find the
explicit expression for the density matrix and concurrence. It is shown that the amount of the transferred entanglement has
a direct connection with the target states and the lengths of the arrays of cavities. Moreover, the influence of the initial
states and the length of the arrays of cavities on the phenomenon of entanglement sudden death is also investigated. |
