Motivated by recent experimental studies on coherent dynamics transfer in three interacting atoms or electron spins [Phys.Rev.Lett 114(2015)113002,Phys.Rev.Lett 120(2018)243604],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 alteatively transfer their entanglement entropy to other two qubit pairs.Thus 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 concurrence.Finally,we discuss an experimental proposal of three Rydberg atoms for testing the entanglement dynamics transfer of this kind.
