Reversible logic adheres to the principles of quantum computation by preventing the wasteful dissipation of energy through heat, unlike conventional calculation mired in thermodynamic inefficiency. Drawing on past frameworks, this study expands the design of reversible carry select adders to a highly scalable 256 qubit architecture. A meticulous examination of salient performance parameters such as quantum cost, spatial compactness, and energy usage is conducted for five proposed reversible CSLA designs. Advanced quantum logical techniques are employed in these architectures to maximize operational proficiency while preserving extensibility. In comparison with traditional designs, the suggested 256 qubit reversible adder achieves more refined spatial optimization and lessens quantum cost, yielding notable increases in computational prowess. It provides a pragmatic alternative for low power digital systems and high performance quantum computing by ensuring expansibility and adaptability.
