Quantum Optics and Sensing in Microgravity

Experiments and scientific exchange in quantum optics and sensing within ground-based and sub-orbital microgravity platforms.

Contributions to QuantumFrontiers

  • Development of scientific projects in Droptowers (Einstein-Elevator, DropTower Bremen, GraviTower Pro) and sounding rockets
  • Development of future geodesy satellite missions, e.g. CARIOQA, by testing atom interferometry in microgravity
  • Realization of atom interferometry in the Einstein-Elevator for research on fundamental physics and metrology beyond the standard quantum limit
  • A collaborative platform for experts on µg-facilities, which improves workflows, experiment quality and project efficiency on current facilities
  • Method and technology transfer on quantum experiments in microgravity via e.g. workshops

Collaborative Innovation

  • Search for dark energy in the Einstein-Elevator (Rasel, Piest, LUH)
  • Interferometry with entangled atoms (Klempt, Kruse, DLR-SI)
  • Extending atom interferometry to unprecedented free evolution times (Rasel, Abend, LUH)
  • Exploring and improving limitations of µg-platforms with respect to vibrations, rotations and magnetic fields beyond current capabilities (Lotz, Herrmann, Becker, LUH, ZARM)
  • Use optical/matterwave high-precision inertial sensors in combination with active controlled stabilization to define the state of the art in µg research (Rasel, Schlippert, Lotz, LUH)
  • Planning, realizing and testing pathfinders for future space missions on microgravity platforms (Rasel, Gaaloul, Lotz LUH)
