Query: Quantized conductance and its correlation to the supercurrent in a
  nanowire connected to superconductors   We report conductance and supercurrent of InAs nanowires coupled to
Al-superconducting electrodes with short channel lengths and good Ohmic
contacts. The nanowires are suspended 15\,nm above a local gate electrode. The
charge density in the nanowires can be controlled by a small change in the gate
voltage. For large negative gate voltages, the number of conducting channels is
reduced gradually and we observe a stepwise decrease of both conductance and
critical current before the conductance vanishes completely.
