We explore fundamental phenomena in quantum optics through experiments with trapped ions, warm atomic vapors, photons, and hybrid systems, including levitated nanoparticles and molecular ions.
Controlled quantum light–matter interactions at the single-particle level provide insight into fundamental quantum processes and support the development of emerging quantum technologies, including quantum communication, sensing, and the simulation of complex quantum systems. Our research focuses on optical, mechanical, and optomechanical interactions in elementary quantum systems. These include the generation, control, and precise measurement of nonclassical states arising from interactions of photons with single, few, or many quantum emitters, as well as from strongly nonlinear light–matter interactions.
Potential applications include the realization of efficient light–matter interfaces, atomic and molecular spectroscopy, the generation of quantum states of light for quantum communication and metrology, and quantum engineering with single-atom oscillators for quantum sensing and testsof the quantum-to-classical transition.
