M.S. In Physics – Quantum Computing Events
Starting from a rubidium Bose-Einstein condensate, recently lowest expansion energies have been achieved by us in the Bremen drop tower as required for extending atom interferometry over several seconds. Exploring these methods to quantum mixtures not only opens up new physics in the absence of buoyancy, but also adds challenges for exploiting these mixtures for interferometry. Interferometers based on two different chemical elements have been proposed for quantum tests of the equivalence principle on the ISS as well as on satellites. Currently, we prepare a sounding rocket mission to investigate the simultaneous generation and manipulation of potassium and rubidium condensates. Together with CAL, these experiments will prepare the DLR-NASA multi-user facility BECCAL for research on quantum gas mixtures and interferometry as well as enhance the readiness level of methods required for STE-QUEST, a proposal for a satellite mission currently studied within ESA’s VOYAGE 2050 program.
