Quantum Physics: Understanding the Incomprehensible

This report presents an introduction to the fundamental principles of quantum mechanics, including superposition, uncertainty, and entanglement. It reviews the historical development of quantum theory, landmark experiments such as the double-slit and Stern–Gerlach experiments, and modern technological applications including quantum computing, quantum communication, and quantum sensing. The report aims to provide undergraduate students with a structured and intuitive overview of the conceptual foundations and practical significance of quantum physics.
