Quantum Information
Quantum information is a rapidly developing cross-disciplinary field of research. It covers research topics varying from modern quantum technological applications, such as quantum communication, sensing and quantum computing, to foundational questions, such as entanglement and non-locality that were in the core of the 2022 Nobel Prize in physics.
We use a mathematical approach towards quantum information theory. Our approach is driven by geometric, topological, and measurement-theoretical approaches with inspiration coming from both contemporary foundational topics and current applications in quantum technologies.
We work on various topics in quantum mechanics, such as Berry phases, measurement incompatibility, weak measurements, quantum steering, and quantum photonics.
