Quantum optics is a field of research that deals with the application of quantum mechanics to phenomena involving light and its interactions with matter. One of the main goals is to understand the quantum nature of information and to learn how to formulate, manipulate, and process it using physical systems that operate on quantum mechanical principles.

The Quantum Information Technology group at Stony Brook University has been active for over six years, publishing numerous scientific papers, focusing on engineering novel quantum memories and processors that will enable future quantum information networks and computing. We develop scalable quantum memories based on solid-state and atomic physics. We use photons to communicate and atoms as nodes to store and process quantum information. Additionally, we develop single photon sources tuned to atomic transitions and design quantum transistors and logic-gates using electromagnetically induced transparency and cold atoms inside optical cavities.
