          Abstract

          In the near future the era of Beyond CMOS will start as the scaling of the current CMOS technology will reach the fundamental limit. QCA (Quantum-dot Cellular Automata) is the transistor less computation paradigm and viable candidate for Beyond CMOS device technology. The complete state of art survey on QCA is presented in this paper. This paper addresses the QCA background, its possible implementation and available simulation and synthesis tools. In depth survey is carried out for the QCA oriented defects and testing. Also, need of development and possible research areas in various sides of QCA are discussed.

          Room temperature magnetic quantum cellular automata

          All computers process information electronically. A processing method based on magnetism is reported here, in which networks of interacting submicrometer magnetic dots are used to perform logic operations and propagate information at room temperature. The logic states are signaled by the magnetization direction of the single-domain magnetic dots; the dots couple to their nearest neighbors through magnetostatic interactions. Magnetic solitons carry information through the networks, and an applied oscillating magnetic field feeds energy into the system and serves as a clock. These networks offer a several thousandfold increase in integration density and a hundredfold reduction in power dissipation over current microelectronic technology.
