Winter Academy 2025

On January 30, 2025, this year's Winter Academy of the Department of Physics took place under the motto "Quantum2025 - 100 years are just the beginning". The event offered school students the opportunity to gain insights into research at TU Dortmund University, particularly into modern quantum physics. More than 20 students were on site, while other interested parties took part in the lectures via Zoom. The event was a complete success.
Quantum mechanics was formulated 100 years ago, in 1925, laying the foundations for our current physical understanding of nature. Today, in 2025, it shapes almost all aspects of our lives. To mark this special anniversary, the year 2025 has been declared the "International Year of Quantum Science and Technology" by the United Nations. The German Physical Society (DPG) is organizing a variety of events and activities under the motto "Quantum2025 - 100 years are just the beginning". TU Dortmund University's Winter Academy was also part of this initiative.
The Winter Academy 2025 offered numerous exciting insights into the world of quantum physics. After a brief welcome and introduction to studying at TU Dortmund University, Apl. Prof. Dr. Doris Reiter opened the lecture series with an overview of future quantum technologies. Doctoral student Alina Joch then explained how quantum systems can be simulated using quantum computers. Junior Professor Dr. Armin Lühr explained how quantum physics is used in medical imaging. Finally, the participants were given a tour of the physics laboratories at TU Dortmund University.

Neuronal cell nuclei are shown in yellow for the granule neurons in the dentate gyrus region of the hippocampus. Blood vessels are shown in red. By changing the X-ray optical magnification in the multi-scale recordings, one can zoom into regions-of-interest (red ovals). In these scans the resolution is high enough to resolve sub-structures of the nucleus, associated with different DNA packing regimes.
