QUEEN - QUantentechnologien für den Einsatz auf Einem Nanosatelliten

A. Dinkelaker, A. Peters and M. Krutzik









The QUEEN project is a Berlin-based collaboration of Humboldt-Universität zu Berlin (HUB) with Technische Universität Berlin (TUB) and Ferdinand-Braun Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH).

Over the course of the project, we study central aspects of space-based quantum technology and the feasability of its integration on nanosatellites.

For the payload, the focus lies on diode laser modules and electro-optical components that are core for optical frequency references. The proposed payload includes a compact laser system with an atomic spectroscopy.

The satellite platform will come from TUB and is similar to that shown in Figure 1. It provides the satellite structure as well as hard- and software for power generation and management, communication to ground, and satellite control.

In a first design study, QUEEN has developed different missions scenarios for optical quantum technology on such a nanosatellite, and estimates their requirements and feasability.

Additionally, qualification tests are performed in order to further laser development for in-orbit applications.
