Quantum leaps are the sole cause of the emission of electromagnetic radiation, including light, which occurs in the form of quantized units called photons. Ironically, when laymen use the term colloquially, they use it to describe large jumps in progress, when in reality a quantum leap is a very small change of state.
The word quantum derives from the Latin, meaning how great or how much. In quantum mechanics, it refers to a discrete unit assigned to certain physical quantities such as the energy of an atom at rest (see Figure 1).uantum mechanics gradually arose from Max Planck 's solution in 1900 to the black-body radiation problem (reported 1859) and Albert Einstein 's 1905 paper which offered a quantum-based theory to explain the photoelectric effect (reported 1887). Early quantum theory was significantly reformulated in the mid-1920s.
