Abstract
More than 99 %-fidelity end-to-end quantum-state and entanglement transfer can be achieved in the ballistic regime of an one-dimensional array of N sites, with N arbitrarily large. The interactions J between nearest-neighbors are uniform all over the chain, except for those involving the first and last bond, say J0, and the second and last-but-one bond J1, with J0File in questo prodotto:
