quantum leap

huge leap, enormous jump

In physics, a quantum leap or quantum jump is a change of an electron from one energy state to another within an atom. It is discontinuous; the electron jumps from one energy level to another instantaneously. The phenomenon contradicts classical theories, which expect energy levels to be continuous. Quantum leaps are the sole cause of the emission of electromagnetic radiation, including that of light, which occurs in the form of quantized units called photons.
