Paper Title:
Efficient Design of QCA Adder Structures
  Abstract

Optimizing arithmetic primitives such as quantum-dot cellular automata (QCA) adders is important for investigating high-performance QCA computers in this emerging nano-technological paradigm. In this paper, we demonstrate that QCA ripple carry adder and bit-serial adder designs actually outperform carry-look-ahead and carry-select adder designs because of the increase in required interconnects. Simulation results obtained by using the QCADesigner tool for the proposed adder designs are also presented.
