Quantum-dot Cellular Automata (QCA) provide very high scale integration potential, switching frequency, and have extremely low power demands, which make the QCA technology quite attractive for design implementation of large-scale, high-performance nanoelectronic circuits. However, state-of-the-art circuit designs were not derived by following a set universal rules, as is case CMOS circuits, and...

   Quantum-dot Cellular Automata (QCA) technology is a solution for implementation of the nanometer sized circuits and it can be a suitable replacement for CMOS. Similar to CMOS technology, designing the basic computational element such as adder with the QCA technology is regarded as one of the most important issues that extensive researches have been done about it. In this paper, a new eff...

Quantum-dot Cellular Automata (QCA) is an emerging and promising technology that provides significant improvements over CMOS. Recently QCA has been advocated as an applicant for implementing reversible circuits. However QCA, like other Nanotechnologies, suffers from a high fault rate. The main purpose of this paper is to develop a fault tolerant model of QCA circuits by redundancy in hardware a...
