Entanglement by environment control in optical cavities (A02)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277625399

We will build up an experiment to study several, individually controllable atoms in an optical microcavity. The goal of the experiments is to demonstrate entanglement between the atoms by dissipative means, whereas, traditionally, dissipation in optical cavities is detrimental to achieving high fidelity of the entangled state, directly contributing to the key questions QA1 (open-system control of quantum states in few-body quantum systems) and QA3 (fundamental aspects of small open systems), which lie at the heart of this CRC. However, for large enough cooperativity between the cavity mode and the atom, dissipative entanglement can be favorable and we aim at achieving and investigating this limit. Moreover, our experimental investigations will explore coupled optical cavities and explore non-linear optical and optomechanical effects in them.
