Nano design of communication parts with QCA using reversible logic

A communication system is implemented as quantum-dot cellular automata. The advance method of Nano technology is Quantum-dot cellular automata (QCA). QCA is a promising alternative to the current CMOS technology. It can be implemented at the Nano scale, reaching ultra-low power consumption. Communication systems are important in current computer systems and it is expected to be even more important in near future. In a bottom-up approach, the Parallel-to-Serial and Serial-to-Parallel converters were described, which are essential to the serial communication. The components for robust communication, such as QCA circuits for Hamming code and Parity Checker are used. The coplanar QCA crossover architecture is used in the design of QCA that leads to the reduction of QCA cell count and area consumption. Reversible Logic design is also used. Reversible logic is found to be Low power design which becomes emerging technology in Low power Nanotechnology era. In this work they devoted to design a Reversible Logic Gate which is a universal gate and can be design with alternative of co-planer cross over wire. They introduce a passive type 3×3 tile that will also helpful for design the co-planner crossover wire.
