Reversible Computing in QCA Based on Toffoli Gate

Abstract

Abstract. Reversible computing is the procedure to future computing technologies, which all occur to use reversible logic. A reversible logic gate has the capability to decrease the power dissipation which is the main requirement in low power Very-large-scale integration design. It has vast applications and related to other emerging technologies such as low power CMOS, quantum computation and nanotechnology. Because reversible logic promises extremely low power consumption with high density and operating frequency. The main target of designing reversible logic is to reduce quantum cost, the extent of the circuits and the number of garbage outputs. The purpose of this paper is to present a new design of reversible logic 3x3 Toffoli gate with low complexity. The proposed design leads to the reduction of power consumption compared with previous logic circuits.
