Quantum

Quantum refers to the smallest discrete unit of any physical property, often associated with the behavior of subatomic particles in quantum mechanics. In this context, it denotes the quantized nature of energy levels, where energy, momentum, and other properties exist in specific, indivisible amounts rather than in a continuous range. The term is foundational to the field of quantum physics, which studies phenomena at atomic and subatomic scales, revealing the complex and often counterintuitive principles that govern the behavior of matter and energy. Quantum theory has led to profound insights and advancements in technology, including the development of lasers, semiconductors, and quantum computing.
