Paperback. Condition: new. Paperback. Quantum Networking in Action provides a practical and accessible guide to the technologies, protocols, architectures, and engineering principles behind quantum communication networks. Written for both beginners and experienced technical readers, the book explains difficult concepts in clear language while maintaining the technical depth needed to understand real network designs, security requirements, performance challenges, and development practices.A major part of the book focuses on entanglement distribution, one of the most important capabilities of advanced quantum networks. You will understand how entanglement is created and distributed, how quantum teleportation transfers quantum state information, how entanglement swapping extends communication across multiple links, and how purification can improve the quality of shared entangled states.Quantum Networking in Action goes beyond theory by examining the engineering challenges involved in building practical networks. You will explore metropolitan quantum networks, wide-area communication, satellite links, infrastructure integration, scalability, performance optimization, network monitoring, and failure management.Security and reliability receive dedicated attention. You will understand the challenges created by implementation weaknesses, side channels, noise, decoherence, detector limitations, synchronization problems, and photon loss. The book also explains the role of quantum error correction, fault tolerance, monitoring, troubleshooting, and performance tuning in dependable network operation.Real application scenarios demonstrate how quantum networking may support secure government and enterprise communication, distributed quantum computing, cloud services, financial systems, healthcare infrastructure, critical systems, and emerging commercial services.Inside this book, you will learn how to: Understand the fundamental principles behind quantum networking and communication.Explore the architecture and operation of the emerging quantum internet.Understand entanglement generation, distribution, swapping, purification, and teleportation.Learn the principles and practical operation of major QKD protocols.Understand quantum repeaters, memories, channels, nodes, and network topologies.Design and evaluate hybrid classical-quantum communication architectures.Explore quantum routing, synchronization, resource management, and protocol design.Build and evaluate quantum networking simulations and practical experiments.Analyze fidelity, latency, photon loss, QBER, secret key rate, and other important performance metrics.Understand security risks, error management, fault tolerance, and troubleshooting methods.Explore real applications and the future development of quantum communication infrastructure.Prepare for emerging standards, interoperability requirements, and next-generation network technologies.Whether you are a software developer, network engineer, cybersecurity professional, researcher, student, systems architect, or technology leader, this book provides a structured path from fundamental concepts to practical network architecture and simulation. Quantum communication is developing rapidly, and the professionals who understand both its physical principles and its networking requirements will be better prepared to evaluate, design, secure, and build the systems that follow.Build your understanding of quantum communication today.

Paperback. Condition: new. Paperback. Advanced RAG Systems provides a practical guide to engineering Retrieval-Augmented Generation systems beyond the basic vector-search-and-prompt approach.You will learn how to design the complete RAG pipeline, from preparing and chunking source data to embeddings, indexing, retrieval, reranking, context construction, generation, evaluation, security, monitoring, and production deployment.The book explains how semantic vector search and BM25 keyword retrieval can work together through hybrid retrieval, helping your system handle both meaning-based questions and exact terms such as product names, identifiers, error codes, and technical references.For more complex applications, the book explores GraphRAG for relationship-heavy and multi-hop questions, Agentic RAG for controlled multi-step retrieval, query routing across different data sources, and adaptive retrieval strategies that can respond when the first search does not provide enough evidence.Inside this practical guide, you will learn how to: - Build reliable RAG data and indexing pipelines- Design semantic, keyword, and hybrid retrieval systems- Combine and rank results using techniques such as Reciprocal Rank Fusion- Apply cross-encoder and LLM-based reranking- Select, compress, and manage retrieved context- Build GraphRAG systems around entities and relationships- Design controlled Agentic RAG workflows- Implement multi-query and multi-hop retrieval- Route queries across different knowledge sources- Evaluate retrieval with PrecisionatK, RecallatK, MRR, NDCG, and other useful metrics- Measure answer quality, faithfulness, grounding, and citation support- Identify and correct common RAG failure patterns- Protect RAG applications against prompt injection, unauthorized retrieval, and knowledge base poisoning- Trace retrieval and generation for better observability- Optimize latency, token usage, retrieval performance, and cost- Scale retrieval, indexing, reranking, and model services- Build and prepare a complete advanced RAG system for productionRather than promoting one framework, vector database, or model provider, this book focuses on practical engineering principles that remain useful as individual technologies change.Whether you are a developer, AI engineer, machine learning engineer, data engineer, software architect, or technical professional, Advanced RAG Systems will help you understand what separates a promising RAG prototype from a system designed for real applications.If you are ready to move beyond basic vector search and build RAG applications with stronger retrieval, better ranking, measurable quality, controlled agentic behavior, and production-ready architecture, this book gives you the practical foundation to do it.Build RAG systems that do more than retrieve information. Build systems that retrieve the right evidence, use it effectively, and produce answers you can evaluate, improve, and trust.Get your copy of Advanced RAG Systems today and start building more capable, reliable, and production-ready RAG applications.
