Quantum Optics

Quantum optics is the study of individual photons and their interactions with atoms and molecules. This includes investigating photons' particle-like characteristics. Photons have been used to test several of quantum mechanics' counterintuitive predictions, such as entanglement and teleportation, and they are a valuable resource for quantum information processing.

Quantum optics is a field of physics that investigates how quantum mechanics can be used to study light and its interactions with matter. Unlike classical optics, which was created by Sir Isaac Newton, the behaviour of individual photons has an impact on the outgoing light in quantum optics. Quantum optics has spawned a number of applications, including lasers. Electromagnetic radiation is seen as both a wave and a particle in quantum optics, a phenomenon known as wave particle duality. The most frequent theory is that photons travel as a stream of particles, but their overall behaviour is regulated by a quantum wave function that defines the likelihood of the particles being in a given location at a given moment.
