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

Abstract

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