The rapid advancements in smart technologies have reshaped the healthcare domain and provided a transformational future in the healthcare domain, particularly in medical diagnosis, automated patient care, and customized treatment. This chapter presents a comprehensive smart healthcare framework that leverages the potential of the Internet of Things (IoT), Quantum Computing (QC), and Blockchain technology in developing an intelligent, secure, and efficient healthcare system through integration of these technologies. IoT enables real-time data acquisition through wearable and implantable sensors. Blockchain guarantees secure and tamper-proof storage and exchange of data. Quantum computing offers immense computing power to process and analyse this data, facilitating precision healthcare, improved diagnosis, and automated patient healthcare. Quantum computing is a paradigm shift in computational efficiency. It harnesses the principles of quantum mechanics, such as superposition, entanglement, and quantum parallelism, thus providing faster and more efficient computing power. Quantum computing can contribute significantly to drug discovery, genomic sequencing, and predictive analytics. A combination of classical computing and quantum computing, referred to as hybrid computing, has the potential to significantly improve early disease diagnosis and customized treatment plans. Quantum-enhanced cryptographic techniques can also provide robust protection to sensitive health data. This chapter emphasizes how the synergy of these cutting-edge technologies can create a resilient, intelligent, and optimal healthcare system, paving the way for more proactive, data-driven, and patient-centric solutions.
