Quantum Dot Cellular Automata (QCA) is an alternative to CMOS technology. The other technologies proposed by researchers are FINFET, CNTs and MTJ to reduce scalability of CMOS devices. Using Quantum Dot Cellular Automata, the low power, extremely dense circuits are designed. QCA cell is the fundamental unit in building logic gates. These cells are powered using specific clock. QCA cells are used to design basic gates and to realize Boolean expressions. QCA Designer tool is used to carry out simulations. The simulation results are same as theoretical results. The complexity and size of circuits are reduced using QCA. The paper includes design of Programmable Logic Array (PLA).
