Summary, etc. Quantum-dot cellular automata (QCA) nanotechnology has the potential for revolutionizing the way computers are used. QCA computing has numerous advantages of ultra-low energy dissipation, improved performance and high device density. An adder is the most elementary component in arithmetic units of processors. Lot of work has been in progress to design and implement efficient adder circuits in QCA nanotechnology. This paper presents design and performance analysis of a new efficient coplanar adder in QCA nanotechnology. The proposed adder design uses 20% less QCA cells as compared to previous similar design due to better arrangement of QCA cells in the layout and has a delay of 1 clock cycle with an area of 0.04 µm<sup>2</sup>. The proposed adder has 19% less average leakage energy dissipation, 28% less average switching energy dissipation, and 25% less average energy dissipation than the best reported previous coplanar adder design. The cost function of proposed efficient adder is equal to best reported previous coplanar adder.
