- 1. Quantum optics is a branch of physics that investigates the interactions between light and matter at the quantum level. It explores how the behavior of individual photons and atoms can be understood and manipulated in the context of quantum mechanics. Researchers in quantum optics study phenomena such as photon entanglement, quantum superposition, and quantum teleportation to develop advanced technologies like quantum computers and secure quantum communication. By harnessing the principles of quantum mechanics, quantum optics has the potential to revolutionize fields such as information technology, cryptography, and metrology.
