Ultracold Atom Cavity Quantum Electrodynamics

Ultracold atoms have advanced over the last couple of years to be one of the most controlled quantum many-body systems. The immense control over the internal and external degree of freedoms of this system makes it an ideal candidate to study a wide range of intriguing quantum many-body phenomena. For the same reason it is also one of the main candidates to be used as a building block in the area of quantum computation and quantum information.

We trap a cloud of ultracold Rubidium atoms inside a high-finesse optical resonator. The optical resonator, also known as cavity, provides a strong coupling of the atoms to a single quantized mode of the electromagnetic field. We study the fundamental behaviours of this interesting many-body system and explore its applicability to quantum information, e.g. as a quantum memory or a quantum repeater.
