Quantum Optics and Sensing in Microgravity

Quantum Optics and Sensing in Microgravity

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


  • Frequent workshops on quantum experiments in microgravity
  • planning, realizing and testing of pathfinders for future space missions on microgravity platforms


  • evolve matter wave interferometry methods in microgravity
  • observing mixtures of quantum gases in absence of buoyancy
  • manipulation and control of atoms/ions in microgravity
  • search for dark energy in the EE
  • Quantum mechanics on large mass scales
  • Ion traps for optical clocks for space applications
  • Exchange of ideas to develop more interesting scientific projects in microgravity
  • Method and technology transfer
  • Connect different microgravity facilities with each other and with the scientists
