Abstract : In this work, a new Quantum-dot Cell Automata (QCA) based cube calculator is proposed with the incorporation of volumetric computation employing next-generation nanotechnology. The contribution is a new and effective architecture that computes volumes correctly with an optimized 3D multiplication circuit based on QCA technology. In contrast to CMOS, the suggested design yields significant gains in area and power efficiency, exhibiting benefits for applications such as autonomous robotics, smart packaging systems, and IoT-capable dimensions measuring devices. The comparative analysis pinpoints the supremacy of QCA design through exceptional performance gains, such as a 97% area reduction and 99% reduced energy consumption compared to its CMOS circuits. The design is found suitable for actual application, which is experimentally validated and verifiably confirmed. The findings emphasize QCA's potential to revolutionize next-generation low-power, high-performance computational units in smart systems.
