Comparison of Complex Gates Using QuantumDot Cellular Automata

[摘要] This paper presents the basics of Quantum Dot Cellular Automata. In this paper two different complex gates such as 7-input complex gate and 5-input complex gate which are designed using QCADesigner tool are compared. An example of four input AND gate using 7-Input complex gate and 5-Input complex gate is taken and their simulation results are shown. All most all the parameters are considered while comparison. Hence it is shown that though the simulation results obtained using both the gates are same, still the 7-input complex gate is the most efficient one.
