Abstract: The changes that the Quantum Cellular Automata devices have faced have been evolutionary but still the most advanced chips continue using the same computing paradigm as their old predecessors. There are a lot of expectations that new paradigms will be developed for the processing of information. The CMOS technology uses current switching but the QCA deals with encoding the binary information as it is the array of cells and every cell has quantum dots and its fast-dimensional scaling will in the end be expected to reach the fundamental limit. The interaction of the quantum mechanics with the coulomb in every cell, is the one that determines the cell state. Additionally, the molecular QCA has the ability of operating at a speed of Terahertz (THz) together with a very less power and extremely high gadget density.
Keywords: Quantum-Dot Cellular Automata, Clocking, Terahertz.
