• The Wigner function is exactly solved and calculated for an idealized one-dimen-sional ballistic channel in which the right and the left electrodes are replaced by ap-propriate boundary conditions and the scattering potential by a delta function, andany scattering mechanisms in leads are absent. The local electron density and the current are evaluated numerically based on this solution. We find the oscillation of theelectron density around the scattering potential closely related to the Friedel oscillalion, and the quantization of two terminal conductance independent of the transmis-sion coefficient of the electron wave. We ascribe this quantization to the strong correlation between two reservoirs through the channel.
