Abstract
Quantum non-locality is here put at variance with spatial contacts, as modelled within the Wigner-Function formalism: we shall show how these two concepts are indeed intrinsically incompatible when applied to transport through quantum devices. More specifically, by means of an exactly-solvable semiconductor model, we show that the application of the usual Up-Wind boundary scheme to the Wigner transport equation may produce highly non-physical results, like boundary-driven negative probability distributions. © 2007 American Institute of Physics.
