Research

My main research area is quantum information theory, with a focus on quantum Shannon theory, communication, learning, and entropic methods. Entropy and related information measures help us quantify what can be transmitted, learned, and preserved when information is processed.

Understanding the differences between classical and quantum information is at the centre of my research. I develop mathematical tools to study these differences and to understand how noise affects information processing in quantum systems.

The following projects and programmes currently support my group.

DFG Research Grant

Project 550206990

Tracking information flow in quantum networks via new divergence measures

How does information change as it passes through a noisy quantum network? This project develops quantum divergence measures to study information loss and its limits. It investigates contraction under noise, including effects on entanglement and coherence, with applications to quantum circuits, network communication, and learning. The aim is to connect mathematical bounds with ways to assess the capabilities of noisy quantum systems.

Funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation), project 550206990.

BMFTR

Grant 13N17418

QUICS

Quantum Innovation and Computing for SMEs

QUICS is a quantum-computing service centre for small and medium-sized enterprises. It helps assess potential applications through algorithm development, simulation, and access to quantum hardware and software. Simulations that account for realistic noise connect the study of quantum algorithms with the conditions in which devices operate. The centre also provides advice and training.

Supported by Germany’s Federal Ministry of Research, Technology and Space (BMFTR) through the QC service centre QUICS, grant 13N17418.

Tracking Information in Quantum Networks

TITAN

Through this fellowship, I worked at TU Munich with Robert König and at the Centre for Quantum Technologies, National University of Singapore, with Marco Tomamichel. The project studied how entropic quantities can be used to understand information flow in quantum networks. The fellowship ended when I moved to Hannover.

This project received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 101025848.
