Critical Study on Quantum-Dot Cellular Automata (Qca)

Abstract

As a new paradigm in electronics for processing and transmitting data, cellular automata based on quantum dots is a fascinating development. The world has taken notice of this groundbreaking microscopic technology. Since the exact same units that are used to produce logic gates may also be utilized to generate cables conveying term logistics, QCA is preferable to other nanoscale digital design concept. In contrast to the limitations of current CMOS technology, the QCA enables operation at frequencies in the THz range and device integration densities roughly 900 times higher. According to the Semiconductor Industries Association's International Roadmap for Semiconductors, this is one of the nanotechnologies of the future (ITRS). As opposed to current flow, QCA cells communicate with one another via Coulombic interaction to perform logical operations and transfer data. The QCA layout takes advantage of emerging technologies like mobile ram and processor via wires. The concept of "storage on the fly" is a subset of "having to process," a broader framework. Information can be manipulated during signal transmission and reception thanks to the processing-by-wire (PBW) capability of QCA. Both the configuration of the cells in an MV and the so-called inverter chain exhibit PBW capabilities. This paper reflects overview of the investigation of Quantum-Dot Cellular Automata (QCA).
