A schematic illustration of an experimental device in which a common continuum supports a non-local coupling between a pair of quantum point contacts. With a localized state present in one of the point contacts, the coupling to the continuum gives rise to a mesoscopic Fano resonance in this open system. For further details see the article by S. Xiao et al.
