Quantum Theory

About

Quantum theory, also known as quantum mechanics, is a fundamental physical theory that explains the behavior of matter and energy at the atomic and subatomic levels. It emerged in the early 20th century from efforts to explain phenomena that classical physics could not account for, such as the photoelectric effect and black-body radiation. Key concepts include wave-particle duality, where particles can exhibit both wave-like and particle-like behavior, and the uncertainty principle, which limits the precision with which certain properties can be measured. Quantum theory forms the basis for various fields, including quantum computing, which leverages phenomena like superposition and entanglement to perform calculations beyond classical computers' capabilities. Quantum computing uses qubits, which can exist in multiple states simultaneously, allowing for exponential scaling in processing power. This technology has potential applications in solving complex problems across multiple industries. Quantum theory's principles have been extensively verified through experiments and continue to influence advancements in physics and technology.
