How will we perform calculations in the future? And what can we actually learn about thinking by studying artificial neural networks? The Leipzig Science Club addressed these questions on September 21, 2026, at the Saxon Academy of Sciences in Leipzig.
Following opening remarks by SAW President Prof. Dr. Hans-Joachim Knölker, Prof. Dr. Marius Grundmann (University of Leipzig / SAW) and Dr. Nico Scherf (MPI-CBS) discussed two fascinating topics for the future.
In his presentation “Quantum Computing with Diamonds: From Qubits to Quantum AI,” Prof. Dr. Marius Grundmann (University of Leipzig / SAW) demonstrated that quantum computers are not simply the next generation of classical computers. They are based on fundamentally different physical principles and thus open up new possibilities for information processing. Particularly impressive was the prospect that quantum computing could enable significantly higher computing power in the future while consuming less energy—especially if the technology, as with the Leipzig-based startup SaxonQ, can be operated at room temperature without the need for complex cooling systems.
Dr. Nico Scherf (MPI CBS) then took the audience on a journey through the “geometry of thought.” In his talk, “The Shape of Thought: Neural Geometry in Brains and Machines,” he made it clear that artificial neural networks and the human brain do not function identically by any means. Precisely for this reason, he argued, a careful examination of the underlying methods is crucial when neural networks are used to analyze biological or cognitive processes. His talk also opened up philosophical perspectives: What does knowledge mean? What can machines actually understand? And how do we arrive at reliable knowledge about thought itself?
In her moderation, Prof. Dr. Dr. Ulrike Köhl (Fraunhofer IZI / University of Leipzig) emphasized Leipzig’s strength as a center of science in these important fields of research and discussed the possibilities for translating this research into practical economic applications.
The evening highlighted just how closely technological innovation, basic research, and social issues are intertwined. The presentations sparked lively discussion during the get-together that followed. Many thanks to the speakers for their presentations, to our guests, and to the Saxon Academy of Sciences in Leipzig for their hospitality. We look forward to the next edition of the Leipzig Science Club in early 2027.
