Design of Quantum Encoders with Minimum Area Overhead

Abstract

AbstractCode converter is widely used for security purposes to protect sensitive data from spies. Code converter transforms data information into any coded form. Code converter is also useful for increasing the controllability and transportability of the data. There is a different way of implementing a code converter in a digital circuit. One way to implement a code converter using Complementary Metal Oxide Semiconductor (CMOS) technology. For reducing the area size, and increasing the power consumption, this paper presents the alternative technologies of CMOS that is Quantum dot Cellular Automata (QCA) nanotechnology. In recent times, QCA is an emerging technology that significantly overcomes the problems in CMOS technology. QCA is small size, low power consumption, and high speed compared to CMOS technology. In this research paper, logic gate-based efficient 4-bit QCA binary to gray conversion nanotechnology is proposed. The proposed technology is validated using QCA designer version 2.0.3. In the resulting phase, the performance is analyzed and verified for determining the capabilities of the quantum based converter.KeywordsBinary to grayCell countCode converterComplementary metal oxide semiconductorQuantum dot cellular automata
