Quantum-dot cellular automata, is an extremely small size and a powerless nanotechnology. It is the possible alternative to current CMOS technology. Reversible QCA logic is the most important issue at present time to reduce power losses. This paper presents a novel reversible logic gate called the F-Gate. It is simplest in design and a powerful technique to implement reversible logic. A systema...

The ternary Quantum-dot Cellular Automata (tQCA) were demonstrated to be a possible candidate for the implementation of a future multi-valued processing platform. Recent papers show that the application of the adiabatic pipelining can be used to solve the issues of the tQCA logic primitives. The architectures of the resulting tQCAs become similar to their binary counterparts and the physical de...

A novel Parity-Preserving Reversible Gate (PPRG) is developed using Quantum-dot Cellular Automata (QCA) technology. PPRG enables rich fault-tolerance features, as well as reversibility attributes sought for energy-neutral computation. Performance of the PPRG design is validated through implementing thirteen standard combinational Boolean functions of three variables, which demonstrate from 10.7...

Quantum-dot cellular automata (QCA) nanotechnology is a practical suggestion for replacing present silicon-based technologies. It provides many benefits, such as low power usage, high velocity, and an extreme density of logic functions on chip. In contrast, designing circuits with no waste information (reversible circuits) may further reduce energy losses. The Feynman gate has been recognized o...
