Zusammenfassung / Abstract

The fundamental question regarding the transition between the seemingly contradictory quantum and classical description of nature has intrigued physicists since the discovery of quantum mechanics.

Further insight on preparing non-classical states in macroscopic systems is expected from creating hybrid quantum systems of entirely different partners.

This thesis details the realization of such a hybrid quantum system consisting of a Bose-Einstein condensate and a cryogenically pre-cooled membrane oscillator. The latter is enclosed by a Fabry-Pérot cavity, representing a membrane-in-the-middle system. A light field mediates the mutual coupling between both systems over a macroscopic distance.
