Design of efficient N‐bit shift register using optimized D flip flop in quantum dot cellular automata technology

Abstract There is a need for secure and powerful nano communication systems with ultra‐low power consumption in the new digital age. Quantum‐dot cellular automata (QCA) is a technology which can be used for designing these systems. In the nano regime, relative to complementary metal oxide semiconduc...
