The Hannover Institute of Technology (HITec) at Leibniz Universität Hannover is a unique interdisciplinary research center worldwide. The new building combines three research directions from the fields of physics and geodesy under one roof: quantum technologies, optical technologies and the development and application of quantum sensors. All three research areas fit closely into the core topics of the two clusters of excellence applied for – QuantumFrontiers and PhoenixD.

The new building offers more than 100 scientists a unique infrastructure. In addition to laboratories that are dimensioned for experiments at quantum level precision, three large-scale facilities that are unique in the world will be used. The Einstein elevator – a 40 meter high free-fall simulator – enables experiments in weightlessness for four seconds. The so-called fiber drawing system is used to develop and produce optical fibers, which are used, for example, as space-suited fiber lasers and in fiber-optic applications. And the atomic fountain (Very Large Baseline Atom Interferometer – VLBAI) is used to research and develop high-precision measurement methods based on matter waves.

During the planning phase, the focus was on the consistent separation of the highly sensitive complex optical systems from the numerous interference pulses.

The drive and guidance concept of the Einstein elevator was specially developed for the large machine and is unique worldwide. Construction components from various fields such as roller coaster construction, machine tool technology and elevator technology were used. On 22 November, a research nacelle with a test capsule was installed in the drop tower, allowing experiments to be carried out under conditions of weightlessness. Compared to classical drop towers, the further development of the large machine offers many advantages, in particular a repetition rate of up to 100 tests per day.
