Stimulated emission (in which photons "clone" themselves) was predicted by Einstein in his kinetic derivation of E=hν, and led to the development of the laser. Einstein's derivation also provoked further developments in the quantum treatment of light, the semiclassical model and quantum electrodynamics (see below).

In quantum field theory, probabilities of events are computed by summing over all possible ways in which they can happen, as in the Feynman diagram shown here.
