A Memory Design in QCAs using the SQUARES Formalism

We present a formalism for implementing circuits with Quantum-dot Cellular Automata (QCA), comprising a set of standard circuit elements with uniform layout rules. The formalism simplifies circuit design from an engineering perspective and overcomes an observed sensitivity of QCA systems to input delays. A design for an addressable shift register is implemented, and promises considerable density gains over conventional CMOS.
