The rapid evolution of smart cities is transforming urban landscapes worldwide with Smart City Applications (SCA), including Smart Parking, Smart Education, Smart Healthcare, and Smart Vehicles. Leveraged by advanced technologies such as the Internet of Things (IoT), Artificial Intelligence (AI), Blockchain (BT), Digital Twin (DT), and 6G networks, these cities are redefining how resources are managed, services are delivered, and metropolitan challenges are addressed. However, the complexity and interconnectedness of these systems introduce significant challenges, including security vulnerabilities, inefficiencies in resource utilization, and growing concerns over privacy. Traditional methods struggle to address the increasing demands for real-time decision-making, scalability, and privacy in interconnected innovative systems. To address these challenges, the integration of Quantum Intelligence (QI)—the convergence of Quantum Computing (QC), Quantum Machine Learning (QML), Quantum Federated Learning (QFL), Quantum Cryptography (QC), and AI—emerges as a revolutionary paradigm. QI offers a transformative approach to addressing the limitations of traditional Smart Cities. With its ability to process vast datasets, perform complex optimizations, and enable secure communication through quantum cryptography, quantum intelligence holds the potential to redefine the future of advanced development. This book is motivated by the urgent need to harness quantum intelligence to overcome these challenges and drive the growth of secure, sustainable, intelligent, next-generation smart cities. In this book, we embark on a journey to explore the profound impact of “Quantum Intelligence for Smart Cities: Secure Services for Next Digital Era”
