Abstract
We perform numerical simulations of the switching characteristics of coupled quantum wires with different potential profiles. Our calculations reveal a reduced efficiency of switching between the wires, when their profile is close to that expected for an experimental implementation of the system. We also demonstrate a novel manifestation of electron-stub-tuner behavior in a slightly asymmetric configuration of the coupled wires
