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 de...

Description
Summary: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.
