Our group performs experiments on foundations of quantum physics, quantum information and communication. We are located at the LMU University of Munich and at the Max-Planck Institute of Quantum Optics in Garching.
Atom-Photon and Atom-Atom Entanglement
In this project we generate and study entanglement of single trapped Rubidium atoms and single photons. It allows combining the advantages of atomic systems, such as long coherence times and the ability to process quantum states, with the capabilities of photons to carry quantum information over large distances.
Entangled photons from parametric downconversion are a versatile resource for quantum information processing, communication and fundamental science.
Free-Space Quantum Cryptography
Secure key distribution is performed via free-space optical links using BB84 protocol.
Single Photon Sources
Luminescent defect sites in diamond are used as efficient single-photon sources.
