Most of our projects are concerned with the creation and applications of entanglement. For the creation of entangled photon pairs we employ semiconductor micro- and nanostructures such as quantum-well microcavities, quantum dots, and Bragg-reflection waveguides. In the future these could be integrated with lasers, active and passive optical elements and even detectors on a single chip. Our long term-goal is the quantum optics lab on a chip. In addition we pursue experiments on the foundations of quantum mechanics and in quantum communication, for example quantum key distribution. (read more...)
