Design for scalability is one of the paramount aspects of nanotechnology. The authors present a new architecture for scalable gates in two-dot molecular quantum-dot cellular automata paradigm. Quantum chemical calculations are performed on multiple molecules that are arranged to carry out logic operations at the nanoscale. Compared to previous multi-input gates in four-dot quantum-dot cellular automata framework, the number of used redox centres has been significantly reduced in the presented gates.
