The transfer of quantum entanglement in a rhombic spins system

We consider the model of a rhombic spin system that consists of four spins. In the model, the spins are coupled with each other by inner and outer Ising interactions. We show that, in the considered system, quantum entanglement can be perfectly transferred from a pair of spins to another one. Besides, we also point out that the quality of transferring is not only dependent on the strength of couplings but also on the kind of the transferred quantum entangled state. Furthermore, the appearance of the inner interaction induces the transfer of entangled states selectively depending on the transferring direction.
