Quantum-dot cellular automata (QCA) is one of the promising next-generation fabrics for circuits. Coplanar wire crossings are one of the more elegant features of this new low-power computing paradigm. Proposed are coplanar wire crossovers using a single type of QCA cells, which has significant implications in fabrication and fault tolerance.
