High-probability quantum state transfer among nodes of an open XXZ spin chain

This Letter concerns the problem of the high probability state transfer among s22s symmetrically placed nodes of the N-node chain of spins 1/2 with the XXZ   Hamiltonian. We consider examples with (N,s)=(4,4)(N,s)=(4,4), (N,s)=(6,4)(N,s)=(6,4) and (N,s)=(8,8)(N,s)=(8,8).
