Recent developments in atom optics allow for ultra precise and accurate measurements at the level of Heisenberg limited uncertainty. These measurements can be performed with ultra-cold quantum gases by extending their time of unperturbed evolution. The pioneering experiment QUANTUS has realized a Bose-Einstein condensate in microgravity and subsequently observed it’s free evolution for up to 1 second. Our second generation experiment QUANTUS 2 will be more compact, allow for larger numbers of atoms and will enhance the time of microgravity to 9 seconds. 87Rb and 40K will be used as a Bose-Fermi mixture in order to perform matter wave interferometry in microgravity and to test the Weak Equivalence Principle in the quantum domain. This will be possible due to the mass independent confining potentials available in a microgravity environment. An up-to-date progress report of our activities and future prospects will be presented.
The QUANTUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR 50WM0835-0839.
