Abstract
The effects of additional cells on the circuit operation of quantum cellular automata (QCA) logic, proposed by Lent et al., are numerically studied using the extended Hubbard model self-consistently. We investigate the differences in logic circuit operation between Lent's inverter and our original 4-cell one characterized by a loop structure in the cases of 4 and 5 quantum dot cells (QDC). We find that the 4-cell inverter with loop structure composed of 4-QDC exhibits favorable characteristics in QCA logic operation.Keywords
