  Motivated by recent experimental study on coherent dynamics transfer in three
interacting atoms or electron spins \cite{Barredo:2015,Rosenfeld:2018}, here we
study entanglement entropy transfer in three interacting qubits. We
analytically calculate time evolutions of wave function, density matrix and
entanglement of the system. We find that initially entangled two qubits may
alternatively transfer their entanglement entropy to other two qubit pairs. So
that dynamical evolution of three interacting qubits may produce a genuine
three-partite entangled state through entanglement entropy transfers. In
particular, different pairwise interactions of the three qubits endow symmetric
and asymmetric evolutions of the entanglement transfer, characterized by the
quantum mutual information and concurence. Finally, we discuss an experimental
proposal of three Rydberg atoms for testing the entanglement dynamics transfer
of this kind.
