Quantum-Dot Cellular Automata (QCA) are an emerging field-coupled nanotechnology with remarkable performance and energy efficiency. In order to enable the exploration of this technology, we propose a model for the logic synthesis of QCA circuits that, for the first time, considers and abstracts all main physical aspects—in particular, energy dissipation. To this end, we review in detail how ene...

the electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting hamiltonian anderson tunneling method. in this paper we concentrate on the configuration of the quantum dot rings. we show that the asymmetric structure of qd-scatter system strongly influences the amplitude an...
