We report a one-dimensional nonlocal experiment where the conductance of a section of carbon nanotube shows regular oscillations due to phase-coherent and ballistic transport in an adjacent section. This occurs in spite of wide strongly coupled contact electrodes, which are expected to divide the nanotube into independent sections. Our simulations show that the electrodes can be modeled as shallow and wide barriers which maintain quantum coherence of electron transport between the adjacent sections for lengths of several micrometers.
