Quantum dot Cellular Automata, shortened to QCA, is a new technology that can make integrated circuits at the nanoscale, high speed, with the ability to compress and reduce power consumption. In conventional technologies such as CMOS, reducing the size and dimensions of the circuit result in reduced efficiency. But in this novel nanotechnology by means of some specific techniques such as multi-layer design, and by minimizing the number of gates per unit area, this problem can to a great extent be improved. In this research which is based on the design of Sequential logic circuits, first a set-reset latch is implemented, then an improved latch is, through employing the above procedures, designed. The simulation process provides evidence of a higher speed circuit and reduction in the area occupied.
