I also work on optimizing our active and passive electronic components for extremely low-noise cryogenic amplification. To do this, I develop CAD models that predict the electrical behavior of the individual components at cryogenic temperatures as accurately as possible. Using these models, we try to achieve improvements in the amplifier circuits, but also of the technology.
How important are collaborations for your work?
Collaborations are enormously important to stay in touch with system developers and users. For example, we have a cooperation with the Max Planck Institute for Radio Astronomy, who uses cryogenic HEMT amplifiers from Fraunhofer IAF in their radio telescopes. We are also working intensively with partners in the quantum computing projects QBriqs and MuniQC-SC. Here we are developing scalable packaging technology for our HEMT amplifier chips, such as small form factor multi-channel modules for reading out qubits. We are also trying to integrate superconducting materials into our amplifiers to achieve even lower noise.
What makes your work here at the Fraunhofer IAF particularly attractive to you?
At Fraunhofer IAF, I have the opportunity to work in a very self-determined way and I can define many of my research topics myself or at least actively help to shape them. I also appreciate the flexible working hours and the independent work here. The possibility to work with the excellent HEMT technology as well as the access to IAF’s high-tech laboratory equipment make working here super attractive for me.
What's next for you in the next few years?
For the time being, I plan to stay at Fraunhofer IAF as a scientist and project manager. My PhD is recent and I would like to further my experience in scientific project management. I also want to remain active in the area of circuit design and modeling.
Do you have a favorite place in Freiburg? If so, can you share it with us?
I like the Cafe Pow very much. The ideal location to enjoy a good cappuccino outside in a courtyard in the usually warm Freiburg summer. Otherwise, I really appreciate Freiburg’s proximity to the Black Forest, where you can go hiking in summer and skiing in winter.
