Leibniz Universität Hannover: Cluster of Excellence QUEST


Based on well established strategic partnerships between Leibniz Universität Hannover (LUH) and renowned scientific institutions in its vicinity as well as industrial partners a unique blend of competence in quantum engineering and space-time research has been accumulated. This body of experience has led to the founding of the interdisciplinary Centre for Quantum Engineering and Space-Time Research, with the acronym QUEST.


QUEST’s structure integrates interdisciplinary science with excellent training focussing on four key areas of research: Quantum Engineering, Quantum Sensors, Space-time Physics, and Enabling Technologies. These are complemented by so called Task Groups, which are cross structures whose purpose is to ensure the optimum flexible response to the challenges identified in the context of the research areas.

Quantum Engineering comprises the theoretical and experimental efforts to explore novel and promising quantum systems and quantum probes made of matter or light, which may serve as platforms for new quantum sensors. Research on quantum sensors is devoted to optical and matter-wave interferometry, as used for gravitational wave detectors or high precision measurements of long distances, to optical clocks, to inertial sensors of unprecedented precision and to novel fundamental tests based on atomic, molecular or mesoscopic quantum systems.

Although the ultimate theory of quantum gravity is not in our hands yet, the leading candidates, namely string theory including extra dimensions, canonical or loop quantum gravity and non-commutative geometry, all suggest specific novel space time phenomena. These will be explored under the headline of space-time physics.


The area of enabling technologies will establish the link between optics of matter waves, photonic waves and latest quantum electronics such as novel laser devices, novel ultra-stable-low-noise optical cavities and novel comb generators. Robust and reliable devices are the key to exploring the potential of quantum engineering and mandatory for the most sensitive experiments and tests in fundamental physics (terrestrial and space-based alike).
