Stephan Weis

Stephan Weis is a Research Fellow in the Department of Control Engineering at the Faculty of Electrical Engineering, Czech Technical University in Prague. He is actively involved in the ROBOPROX project, focusing on advanced mathematical research at the intersection of convex analysis, variational calculus, and quantum information theory. His work contributes significantly to theoretical foundations in quantum computing and matrix analysis.

Weis's research interests span multiple interconnected fields including Convex Analysis, Variational Calculus, Quantum Information Theory, Matrix Systems, Numerical Ranges, and Operator Theory. His work demonstrates a strong mathematical foundation applied to quantum mechanical problems, particularly focusing on the geometric and topological properties of quantum states and matrix systems. Through his publications, he has established expertise in analyzing the structure of density matrices, numerical ranges, and convex sets in quantum information contexts.

Analysis of his 15 most recent publications (2014-2025) reveals a consistent research trajectory centered on the mathematical foundations of quantum information. His work frequently explores convex geometry applied to quantum states, numerical ranges of matrices, and maximum-entropy principles. A notable pattern shows increasing focus on the topological properties of quantum state spaces and the mathematical structures underlying quantum information processing. His research often involves collaborations with prominent researchers in the field including Didier Henrion, Milan Korda, Martin Kružík, and others.

Weis maintains active scholarly engagement through conference presentations at venues such as IWOTA (International Workshop on Operator Theory and Applications), STOC (ACM Symposium on Theory of Computing), and specialized quantum information workshops. His work appears in prestigious journals including Advances in Operator Theory, Journal of Convex Analysis, SIAM Journal on Applied Algebra and Geometry, and Journal of Mathematical Physics.
