This paper presents a reversible nano‐scale decoder circuit. The decoder is designed by utilizing the new quantum‐dot cellular automata (QCA) format of the QCA1 gate. This QCA1 gate provides 34.25% less cell count with 54.37% less area than the best existing designs. Thus, the proposed QCA1 gate provides less area considering the best existing state‐of‐the‐art plans. The IBMQ‐based quantum realization...
This article describes designing a low‐power novel circuit for overflow detection in two's complement arithmetic operations. The quantum‐dot cellular automata (QCA) is employed to achieve the nanoscale design. For designing the circuit of the proposed arithmetic overflow detector, a new layout of the QCA full adder is utilized. Two different designs of arithmetic overflow detectors are outlined in...
