    The Internet of Things (IoT) is a network of interconnected devices that collect, monitor, analyze, and exchange data. This technology plays a crucial role in the smart city infrastructure by seamlessly interconnecting various nodes. The extensive application and recognition of IoT across multiple city domains, such as healthcare, transportation, energy, education, and agriculture, bring significant challenges, with security among the most pressing. Traditional hardware technologies like Complementary Metal Oxide Semiconductor (CMOS) and Very Large Scale Integration (VLSI) suffer from limitations such as high power consumption and insufficient scalability, which hinder secure and sustainable IoT deployment. Such limitations have prompted the need to seek other technologies that would serve the dual purpose of providing security as well as energy. Quantum-based technologies can become adequate candidates offering promising solutions to make IoT devices and sustainable systems more secured. Quantum-dot Cellular Automata (QCA) has been proposed as a nanotechnology with the potential of consuming ultra-low powers, less area, and high-speed operation. QCA enhances security through sustainable computing objectives by minimizing energy usage. To improve the future security and efficiency of IoT hardware, this paper suggests a QCA-based Arithmetic Logic Unit (ALU). This ALU can generate more than 12 logical and arithmetic operations. Designed together with the majority gates, XOR gates, multiplexers, and full adders, the ALU is simulated using the QCA-Designer 2.0.3. Simulated results indicate improvements in the number of cells and reduced occupied area relative to the earlier designs. These results indicate the potential of QCA technology in enabling secure, energy-efficient, and compact computing architecture applicable in the future IoT.

    Proposing and Developing Low-Power Quantum Arithmetic Logic Units (QALUs) for Smart Grids and the Internet of Energy
    (IEEE, 2025) Ahmadpour, Seyed Sajad; Zohaib, Muhammad; Rasmi, Hadi; Navimipour, Nima Jafari; Alsaleh, Omar I.
    The advancement of modern power systems has produced smart grids by implementing intelligent control systems linked with digital communication technology to boost reliability and sustainability while improving operational efficiency. The Internet of Energy (IoE) represents an advanced version of smart grids that adopt real-time monitoring with decentralized energy management and dynamic power distribution to maximize energy efficiency. The development of the IoE encounters major obstacles because it handles problems involving power consumption, alongside calculation speed, network stability, the protection of information resources, and problems related to system performance management. The solution to these difficulties demands innovative technological methods for implementation. The authors present Quantum Arithmetic Logic Units (QALUs), which serve as a groundbreaking technology for optimizing performance and energy usage in smart grids, together with IoE systems. The combination of nanotechnology elements with quantum computing rules enables QALUs to operate with minimal power requirements alongside simultaneous processing features and error-resilient operations, which suits them for immediate energy supervision purposes. The QALU design proposal demonstrates the evaluation of power efficiency performance while showing operational accuracy levels and scalability capabilities for a future energy network revolution. The proposed ALU brings improvements in all areas, including power consumption, with a 99.29results. This paper marks a transformative advancement in the development of quantum-enhanced smart grids, which pave the way for enhanced, sustainable, and secure optimized energy systems.
