Bridging the gap between nanomagnetic devices and circuits

— This paper looks at designing circuit elements that will be constructed with nanoscale magnets within the Quantum-dot Cellular Automata (QCA) computational paradigm. In magnetic QCA (MQCA) logical operations and dataflow are accomplished by manipulating the polarizations of nanoscale magnets. Wires and gates have already been experimentally demonstrated at room temperature. However, to realize more complex circuits – and eventually systems – more than just wires and gates in isolation are required. For example, gates must be inter-connected, signals must cross, etc. All structures must be controlled by the envisioned drive circuitry. In this paper, structures that will facilitate these circuit-level tasks are presented for the first time.
