Quantum optics

Definition

Quantum optics is the study of how individual quanta of light, known as photons, interact with atoms and molecules. This includes studying the particle-like properties of photons. Photons have been used to test many of the counter-intuitive predictions of quantum mechanics, such as entanglement and teleportation, and are a useful resource for quantum information processing.
