There has been considerable research on quantum dot cellular automata (QCA) as a new computing scheme in the nano-scale regimes. The basic logic element of this technology is majority voter. In this paper, a detailed simulation-based characterization of QCA defects and study of their effects at logic-level are presented. Testing of these devices is investigated and compared with conventional CMOS-based designs. Unique testing features of designs based on this technology are presented and interesting properties have been identified.
