Design and Performance Evaluation of Fault Tolerant Quantum Dot Cellular Automata Based Circuits for Low Power Nano Devices

Abstract

The International Technology Roadmap for Semiconductors (ITRS) expanded its scope not only focused on the memory and microprocessor devices which was driven by traditional Mooreand#8223;s Law but also to the analog and mixed-signal technologies for various applications which was now referred as More than Moore white paper published in 2021. International Roadmap for Devices and Systems Characteristics (IRDS 2022) forecasted about the era of new technologies which not only work at higher speed and also occupied less space as compared to the traditional transistor technology. The nano computing devices are the emerging technology as the semiconductor devices reached to nano scaled level and not easy to keep in pace with the issue raised in nano devices, thereby requirement to develop and synthesis the quantum electronics. The quantum computing required further development and must have low error rates and scale up the designs which indicate the promising future in the upcoming applications. More research need to be carried out in the area of developing the quantum electronic circuits and algorithms. It is the vision of IRDS and IEEE to simulate the selection process to integrate the quantum electronics in 2030 and beyond. The quantum computing will replace the traditional computing schemes and algorithms, thereby requirement to develop the quantum circuits for the futuristic nano devices. The Quantum Cellular Automata (QCA) is the latest research area where various researcher are working to develop the digital circuits for nano computing devices which is successor for CMOS transistor technology, implemented by using quantum dots. newline
