*Quantum optics* is a branch of [[Quantum Mechanics|quantum physics]] that deals with the interaction between [[light]] and matter. Quantum optics investigates how photons, the elementary particles of light, interact with atoms, molecules and other quantum mechanical systems. It is fundamental to the understanding and development of many quantum technologies. >[!read]- Further Reading >- [[Quantum Mechanics]] >- [[Photon]] >[!ref]- References
