Abstract

Quantum-dot Cellular Automata (QCA) is a novel and potentially attractive technology for implementing computing architectures at the nano-scale. The basic Boolean primitive in QCA is the majority gate. In this study we present a novel design for QCA cells and another possible and unconventional scheme for majority gates. By applying these items, the hardware requirements for a QCA design can be reduced and circuits can be simpler in level and gate counts. As an example, a one bit QCA adder is constructed by applying our new scheme. Beside, we prove that how our reduction method decreases gate counts and levels in comparison to the other previous methods.
