Quantum Optics and Photonics

The study of how individual units of light, or photons, interact with atoms and molecules is known as quantum optics. This includes researching photons' particle-like characteristics. It is helpful for both quantum communication and quantum information processing. It applies to both straightforward and intricate quantum systems, including atoms and molecules. Long-distance quantum teleportation between atomic systems has been established by recent research.

Quantum photonics is the science of creating, controlling, and detecting light in regimes where individual quanta of the light field may be coherently controlled (photons). The EPR paradox and Bell test experiments, for example, have used quantum photonics to investigate quantum phenomena. Quantum photonics is also predicted to play a crucial role in the development of future technologies including quantum computing, quantum key distribution, and quantum metrology. Photonic integrated circuits are used in integrated quantum photonics to control photonic quantum states for applications in quantum technology.
