MiQuE - Compact modules for mobile, free-beam quantum communication

The research project "Miniaturized Quantum Key Entity" (MiQuE) aims to develop compact modules for quantum key distribution (QKD) suitable for mobile applications and secure communication over shorter distances. The project includes the development of modules for QKD key generation, signal detection and integration into VPN environments. Special attention is given to the use of free-form optics and the optimization of thermal concepts to reduce energy consumption. The project offers high innovation potential and is intended to strengthen Germany's technological sovereignty in the field of quantum communication.

In the overall project, Fraunhofer IPMS is generally responsible for the tasks of concept development and requirements analysis. In this context, the detailed concept for the optical channel will be developed, including the definition of interfaces and responsibilities as well as the preparation of the specifications. A simulation environment is set up to design and optimize the optics and to investigate the interaction of the components of the optical channel. In particular, Fraunhofer IPMS is responsible for the design and development of a beam steering device for the automatic alignment of the optical channel (beam steering). Furthermore, the IPMS develops the interfaces of the beamsteering module, the TX and RX optics and the control concept for beamsteering. The development of the transmit and receive modules of the beamsteering system also falls within the scope of the IPMS.
