Theory of photon coincidence statistics in photon
... This is a nonlinear process in which each of the photons of a pump interacts with a medium exhibiting a second-order nonlinear effect and creates a twin pair of photons called signal and idler. Conservation of momentum ensures that if one photon is observed in one direction, its twin must be present ...

A Motivation of Quantum Mechanics
