Biosensing technologies are experiencing a major transformation driven by advances in artificial intelligence, quantum computing, and distributed digital infrastructures. Classical artificial intelligence (AI) has already demonstrated significant value in biosensing through improved signal processing, pattern recognition, and data-driven diagnostics. However, the increasing complexity of biosensor data, together with challenges such as limited datasets, noise, and real-time decision-making requirements, highlights the limitations of purely classical approaches. Quantum artificial intelligence (QAI), which combines quantum principles such as superposition, entanglement, and hybrid quantum–classical learning, offers a promising alternative by enabling improved feature extraction and enhanced performance in data-constrained environments. In parallel, blockchain technology introduces a decentralized and secure framework for managing biosensing data, supporting integrity, traceability, and trust in distributed diagnostic and monitoring systems. This chapter presents a comprehensive overview of classical AI, quantum AI, and blockchain technologies as applied to next-generation biosensing systems. It discusses their individual roles, synergies, and integration into unified architectures for secure, intelligent, and resilient biosensing. Applications in healthcare diagnostics, environmental monitoring, and point-of-care testing are highlighted, alongside key challenges, ethical considerations, and future research directions toward quantum-ready and trustworthy biosensing ecosystems. In addition, the chapter considers how these technologies may support the development of more adaptive biosensing platforms capable of learning from diverse data sources, operating across decentralized healthcare environments, and maintaining data security throughout the diagnostic workflow. Emphasis is placed on the importance of interdisciplinary design, where biosensor engineering, quantum machine learning, quantum information science, blockchain and biomedical development converge to address practical diagnostic challenges.

The convergence of quantum computing, blockchain technologies, and contextual artificial intelligence offers a transformative opportunity to meet the growing demands of secure, adaptive, and decentralized systems. However, most existing approaches focus on isolated or pairwise integrations of these technologies and do not provide a comprehensive architectural synthesis. This paper introduces a quantum-classical hybrid architecture that unifies quantum-enhanced cryptographic processing, blockchain-based trust mechanisms, and context-aware AI reasoning within a modular and interoperable system design. The proposed architecture consists of four interoperable layers: a quantum layer for cryptographic functions and computational enhancements, a classical layer for coordination and orchestration, a contextual AI layer for real-time inference and adaptation, and a blockchain layer for transparent and tamper-resistant record keeping. A key innovation of this architecture lies in its use of contextual AI models, such as transformers, to interpret dynamic environments and guide decisions across quantum and blockchain components. This paper presents use cases in healthcare, finance, and supply chain domains which are theoretical, yet based on realistic challenges and operational demands. These scenarios illustrate how each layer of the architecture contributes to practical decision-making, enhancing the feasibility of future deployments. The paper also discusses implementation challenges such as quantum hardware limitations, integration complexity, and data privacy, and outlines a trajectory for advancement through quantum middleware, explainable AI, and post-quantum cryptographic integration. By aligning emerging technologies within a unified structure, this study offers a forward-looking blueprint for secure, intelligent, and context-aware systems in decentralized environments.
Artificial Intelligence (AI) is revolutionizing diagnostics by enhancing the capabilities of quantum imaging (QI) and quantum sensors (QS) in healthcare.
