This document discusses the concept of quantum computing. It begins with an introduction and overview of topics to be covered, including definitions, history, technologies, applications and future scope. The core concepts of quantum computing are then explained, such as qubits, superposition, and entanglement. The history section outlines major developments, including early proposals in the 1980s, early working models in the 1990s, and advancements by companies like D-Wave today. The document concludes by noting that while quantum computing is still in pioneering stages, it could one day lead to major advancements in areas like optimization, machine learning, and database searches.
