abstract = {We report on a prototype device geometry where a number of
quantum point contacts are connected in series in a single
quasi-ballistic InAs nanowire. At finite magnetic field the
backscattering length is increased up to the micron-scale
and the quantum point contacts are connected adiabatically.
Hence, several input gates can control the outcome of a
ballistic logic operation. The absence of backscattering is
explained in terms of selective population of spatially
separated edge channels. Evidence is provided by regular
Aharonov−Bohm-type conductance oscillations in transverse
magnetic fields, in agreement with magnetoconductance
calculations. The observation of the Shubnikov−de Haas
effect at large magnetic fields corroborates the existence
of spatially separated edge channels and provides a new
means for nanowire characterization.},
