Quantum cellular automata (QCA) is the most recent creating innovation for rapid, low power computation architectural technique in the field of new-age nanoelectronics that restructures the logical information as charge structures of as a Quantum cell which was firstly suggested by Lent et al. [ 1 ]. The Quantum-Dot cellular automata are an alternative for conventional CMOS technology to implement classic cellular automata with quantum dots. The use of quantum cell automata is an innovation as an option to CMOS technology on the nanoscale has a promising future as its integration with various digital circuits in a precisely low powered device. This chapter analyzes the QCA based flip-flops and proposed novel layouts of shift register and ring counter with less QCA cells and better performance parameters. The SISO shift register and ring counter is structured using a D flip flop which is redesigned using 38 cells, show 42% less complexity than previous structures.
