Query: Multipartite entanglement transfer in spin chains   We investigate the transfer of genuine multipartite entanglement across a
spin-1/2 chain with nearest-neighbor XX-type interaction. We focus on the
perturbative regime, where a block of spins is weakly coupled at each edge of a
quantum wire, embodying the role of a multiqubit sender and receiver,
respectively. We find that high-quality multipartite entanglement transfer is
achieved at the same time that three excitations are transferred to the
opposite edge of the chain. Moreover, we find that both a finite concurrence
and tripartite negativity is attained at much shorter time, making
GHZ-distillation protocols feasible. Finally, we investigate the robustness of
our protocol with respect to non-perturbative couplings and increasing lengths
of the quantum wire.
