The aim of QUANTUS-II is to test the weak equivalence principle in the quantum domain using matter-wave interferometry. To this end, a degenerated Bose-Fermi mixture of 87Rb and 40K will be created in microgravity to take advantage of an extended time of free evolution. Our compact atom chip based setup can employ the catapult mode of the drop tower in Bremen, which provides up to 9 seconds of microgravity.
The poster shows the setup, the up to date progress and future prospects of this ambitious and technically challenging project.
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 50 WM 1131.
