A New Quantum-Based Building Block for Designing a Nano-Circuit with Lower Complexity

Next-generation nano-scale computational systems are being hampered by two significant obstacles: shrinking transistor size and power dissipation. Moore's law does not hold when reaches the atomic level. So, it becomes necessary to investigate alternative technologies that surpass traditional Complementary Metal Oxide Semiconductor ( CMOS ) technology's physical constraints. Quantum Dot Cellular Automata QCA ), a transistor-free paradigm, is thought be best technology for designing logic circuits. However, many designs cut energy usage offer straightforward access inputs outputs. Moreover, adders, primary component in circuits digital arithmetic, crucial development of several efficient designs. In this context, 4-bit Ripple Carry Adder RCA type adder can help produce with minimal space consumption because its exceptional qualities. The synthesis high-level further demonstrates design's effectiveness. outcomes QCADesigner demonstrated proposed less complicated use than earlier compared conventional design approaches.
