Quantum communication networks: Design, reliability, and security

The overall purpose of this study is to explore the potential of quantum-based communication networks, leveraging the unique properties of quantum entanglement and superposition, to address critical applications, such as image processing, machine learning, data mining, and encryption. Additionally, this research aims to overcome the limitations of traditional binary systems in the field of computing. The basic methodology of this research involves a comprehensive investigation into the establishment of end-to-end entanglement between two quantum computers, which is fundamental for building robust quantum networks. Performance measures for quantum computers within the context of quantum networks are defined and evaluated, with a specific focus on network design, reliability, security, and trust. Quantum-dot cellular automata (QCA) devices are introduced as a technological advancement to enhance security and trust mechanisms within quantum communication networks.
