Quantum-dot cellular automata (QCA) technology has been widely considered as an alternative to complementary metal-oxide-semiconductor (CMOS) due to QCA’s inherent merits. Many interesting QCA-based logic circuits with smaller feature size, higher operating frequency, and lower power consumption than CMOS have been presented. However, QCA is limited in its(More)
Quantum-dot cellular automata (QCA) is a promising nanotechnology which has potential applications in future computers. Its advantages such as faster speed, smaller size and lower power consumption than CMOS are very attractive. Universal logic gates have stronger function than traditional logic gates. This paper begins with a review of QCA,i.e. basic(More)
