TLDR
The major advantage is that the optimized layouts of reversible gates did not utilize any rotated, translated QCA cells, and offer single layer accessibility to their inputs and outputs, and the proposed efficient layouts did not employ any coplanar or multi-layer wire crossovers.About:

Toward Efficient Design of Reversible Logic Gates in Quantum-Dot Cellular Automata with Power Dissipation Analysis
TL;DR: QCA is investigated as an implementation method for designing area and power efficient reversible logic gates by incorporating a compact 2-input XOR gate and energy analysis confirms that the average energy dissipation of the developed Feynman, Toffoli, and Fredkin gates is less compared to best reported designs.

Quantum Cellular Automata
TL;DR: In this article, the authors proposed a new paradigm for computing with cellular automata (CAS) composed of arrays of quantum devices, which is called edge driven computing (EDC), where input, output and power are delivered at the edge of the CA array only; no direct flow of information or energy to internal cells is required.
