abstract={In this paper, different circuit arrangements of quantum-dot cellular automata (QCA) are proposed for the so-called coplanar crossing. These arrangements exploit the majority voting properties of QCA to allow a robust crossing of wires on the Cartesian plane. This is accomplished using enlarged lines and voting. Using a Bayesian network (BN) based simulator, new results are provided to evaluate the robustness to so-called kink of these arrangements to thermal variations. The BN simulator provides fast and reliable computation of the signal polarization versus normalized temperature. It is shown that by modifying the layout, a higher polarization level can be achieved in the routed signal by utilizing the proposed QCA arrangements},
