Dear colleagues,

We are pleased to announce that applications are now open for the seminar, Operator Theory and Polynomial Optimization in Quantum Information Theory, to be held at the Physikzentrum Bad Honnef from March 11 to March 14, 2025. The application deadline is January 19, 2025.

Quantum correlations are central to the foundations of Quantum Information Theory and for many of its applications. However, their characterization is challenging. Existing mathematical and algorithmic approaches, based on operator theory and non-commutative polynomial optimization, are not adapted to some recent theoretical, experimental, and technological developments in quantum physics, specifically for quantum network correlations. In recent years, this challenge has attracted researchers from quantum theory, operator theory, polynomial optimization, and mathematical physics. While some progress has been made in each of these fields, a compartmented approach for each community cannot work.

The goal of our Operator Theory and Polynomial Optimization in Quantum Information Theory seminar is to bring together world-leading experts and promising early-career researchers to unlock these mathematical barriers. The seminar will make the mathematical approaches from the operator theory and advanced tools from polynomial optimization available to quantum information researchers.
