This talk delves into the transformative potential of quantum computing, a revolutionary technology that leverages the principles of quantum mechanics to perform calculations at unprecedented speeds. We will examine foundational concepts such as superposition and entanglement, which enable quantum bits (qubits) to represent multiple states simultaneously, vastly increasing computational power. Key algorithms, including Shor's Algorithm for efficient integer factorization and Grover's Algorithm for enhanced search capabilities, will be discussed, highlighting their implications for cryptography and data retrieval. Furthermore, we will explore the diverse applications of quantum computing across various sectors, including finance for risk analysis, healthcare for drug discovery, and logistics for optimizing supply chains. The presentation will also introduce the International Year of Quantum Science and Technology (IYQ2025), an initiative aimed at raising global awareness and fostering collaboration among researchers, industry leaders, and policymakers. By addressing both the challenges and opportunities presented by quantum technology, this presentation aims to provide a comprehensive overview of its potential to reshape our technological landscape.
