  We exploit the inherent entanglement of the ground state of a spin chain with
dimerized XX or XXZ Hamiltonian to investigate the entanglement generation
between the ends of the chain. We follow the strategy has been introduced in
Ref. [14] to encode the information in the entangled ground state of the system
by local rotation. The amount of achieved entanglement in this scheme is higher
than the attaching a pair of maximally entanglement scenarios. Also, our
proposal can be implemented by using the optical lattices.
