Overview

As the limitations of CMOS technology become increasingly evident—especially in terms of power dissipation, miniaturization, and quantum effects—there is a pressing need to explore alternative computing paradigms. Quantum Dot Cellular Automata (QCA) offers a promising post-CMOS technology that enables ultra-dense, low-power logic design without traditional transistors. Despite its potential, QCA remains largely underexplored in academic curricula and industry training programs. Most students and researchers are unaware of its principles, design methodologies, and simulation tools. Therefore, this workshop is designed to bridge the knowledge gap, introducing participants to the fundamentals, current research, and practical applications of QCA in digital logic design.

Objectives

• Introduce the limitations of traditional CMOS technology and the motivation for exploring post-CMOS alternatives like QCA.
• Familiarize participants with the principles of Quantum Dot Cellular Automata, including QCA cells, polarization, and basic QCA operation.
• Explain the design and implementation of basic logic gates using QCA, such as majority gates, inverters, and XOR gates.
• Provide hands-on training with QCA simulation tools for circuit design and energy analysis.
• Highlight current research trends, applications, and challenges in QCA-based logic design.

Focus Areas

• Fundamentals of Quantum Dot Cellular Automata (QCA) principles and post-CMOS motivations
• Design and simulation methodologies for QCA logic circuits
• Fabrication techniques and material considerations for QCA devices
• Performance modeling and analysis of QCA-based systems
• Integration of QCA technology with CMOS platforms
• Applications in low-power and high-density nanoelectronic systems
