Cold Atoms in Space

Cold Atoms in Space

Implementing new ideas in fundamental quantum gases physics in the BECCAL orbital ISS facility to benefit from extended microgravity.


  • Explore fundamental aspects in cold and ultra-cold physics
  • Foster collaborations and common publications of QuantumFrontiers scientists and externals
  • Identify science cases where extended microgravity is opening new avenues
  • Prepare for future space experiments and enhance the involvement of QuantumFrontiers scientists
  • Create a platform for frequent multi-disciplinary discussions


  • Quantum mechanics tests
  • Quantum bubbles
  • Tunneling physicsFeshbach molecules
  • Atom-surface physics
  • Scalar Bose gases in light boxes
  • Squeezing experiments
  • Atomic transport and quantum state engineering
