Quantum-dot cellular automata is a cutting edge enumeration methodology that suggests less area and high speedcompare CMOS methodology. The CMOS circuitry having issues related to short channel and device density so QCA is betterand powerful alternative to reduce the area as well as increase the speed of the circuitry. QCA could be a modern computinginnovation that’s made of quantum cell containing two electrons and dots. A multiplier is a vital part of Digital SignalProcessing (DSP) and many more digital circuits applications. We emphasize Vedic multiplier topologies structures agreeingto Vedic science from old Indian figures. In this article, we suggested a efficient, less complex Vedic 22 and 44 multiplierstopologies using proposed ultra efficient Half Adder (HA), Full Adder (FA) topologies in QCADesigner simulationenvironment for less energy and fast speed for nano computing application. The simulation waveform suggests an architectureoutstrip in comparison to the parameters of cell count, area, latency related to past QCA layouts. The proposed QCA 22Vedic multiplier design shown 37.62% improvement in QCA cell count and 44 Vedic multiplier design shown 71.72%improvement in cell counts as well as 29.62% area is decreased for 22 QCA Vedic multiplier and 43.38% area decreasedfrom 4 4 QCA Vedic multiplier as related to its best existing designs.
