Stable optical and vacuum systems for quantum technology applications in space — •Moritz Mihm1, Sören Boles1, Jean Pierre Marburger1, André Wenzlawski1, Ortwin Hellmig6, Patrick Windpassinger1, and the MAIUS Team1,2,3,4,5,61Institut für Physik, JGU Mainz — 2Institut für Physik, HU Berlin — 3IQO, LU Hannover — 4FBH, Berlin — 5ZARM, Bremen — 6ILP, UHH Hamburg

Space-based quantum technology applications face harsh stability requirements while making high demands on system size and mass. We have developed a Zerodur based optical bench system for highly robust and miniaturized optical systems that overcomes these hurdles and that we are currently extending to include vacuum systems. I will present the fundamentals of our technology and the optical modules of MAIUS-2 as an example application. MAIUS-2 is a quantum gas experiment performing atom interferometry with Bose-Einstein condensates of potassium and rubidium onboard a sounding rocket.

Furthermore, I will discuss current efforts to build Zerodur based vacuum systems. The miniaturization of the chamber in conjunction with our laser system technology allows the development of highly robust and fully integrated quantum optical systems for space and other field applications.

Our work is supported by JGU Stufe 1 Funding and the German Space Agency DLR with funds provided by the Federal Ministry for Economic Affairs and Energy (BMWi) under grant numbers 50 WP 1433 and 50 WP 1703.
