An Efficient Design of Multi-logic Gates Using Quantum Cellular Automata Architecture

Abstract

Quantum Cellular automata (QCA) is one of the promising next-generation technology which enables high performance and low energy Nano-electronic circuits. QCA presents a new dimension of ideas of designing the fundamental gates in digital electronics with minimum hardware. Here the logic level switching depends on the change in the polarization between the cells neglecting the current transfer which marks this viable technology as a promising candidate for upcoming generations. Moreover, the processing and transfer of information make use of quantum mechanics and cellular automata to deal with the disputes of CMOS transistor technology. In this manuscript, we have proposed the design of multi-logic gates using QCA architecture. The design layout has been simulated using QCA designer 2.0 and is in accordance with the desired logic. The results are compared with the existing design and found with less number of cells and less area.
