Quantum computing has recently moved from a theoretical concept to a transformative and increasingly accessible computational paradigm. These developments sparked growing interest in the database community along two complementary directions: applying quantum techniques to improve database tasks, and leveraging DBMS principles to support quantum workloads. This three-hour tutorial provides a bidirectional, practice-oriented treatment of this intersection, covering quantum foundations, optimization algorithms, a systematic survey of Quantum-for-DB and DB-for-Quantum research, and end-to-end system integration with a real DBMS. The tutorial includes hands-on demonstrations using quantum simulators and real quantum hardware. We summarize open challenges and research opportunities for practical real-world deployment.

The deeper into space, the more secure and high-speed missions targeting Mars and lunar habitats are needed. As our needs for secure and high-speed communication and also for powerful computing capabilities grow increasingly critical, it becomes evident that classical systems are not capable of meeting the extreme demands of space. This chapter explores how recent advances in quantum computing and quantum communication could come forward to meet these challenges head-on. Based on QKD and entanglement-based protocols of communication, it investigates how mission data, commands, and telemetry can be shielded from intercept or tamper also how some complex calculations and various data processing tasks that require quantum computing can be performed in deep space. Real world projects regarding Micius satellite of China act as case studies to demonstrate how theory is pitted against practice. In addition, the major technical hurdles are outlined, ranging from photon loss to synchronization problems. The path ahead for enabling the next generation of space communications infrastructure is also presented.

Quantum computing has the potential to transform a wide range of fields, such as materials science, chemistry, and optimization issues. The prohibitive expense of proprietary frameworks has severely limited the development of quantum computing systems, despite their transformative potential. Wider involvement in quantum research and development is now possible because of the emergence of open-source quantum computing frameworks as collaborative and affordable alternatives. With a particular focus on different frameworks, this study explores the effectiveness of open-source quantum computing frameworks in improving recommendation systems. In tackling challenging quantum computing problems, the study thoroughly assesses the usability, scalability, and performance of the framework. The results and analysis demonstrate the scalability and performance of different frameworks while utilizing their open-source nature to encourage cooperation and creativity. This study advances quantum-enhanced recommendation systems by bridging the gap between academic research and real-world applications. It also provides practitioners, developers, and researchers who want to use open-source quantum computing frameworks with insightful information to meet their computational needs. The authors aim to extend this research by exploring novel hybrid quantumclassical systems tailored for real-time applications. Future work will focus on integrating error-corrected quantum frameworks to overcome scalability challenges and advance their utility in healthcare and personalized services. This study advances quantum-enhanced recommendation systems by bridging the gap between academic research and real-world applications, providing practitioners and researchers with insight into using open source quantum computing frameworks.
