RESEARCH

We study models for quantum information processing and fundamental aspects of quantum information theory. One focus of our research is the theory of measurement-based quantum computation, which has resulted in a new and more thorough understanding of many-body entanglement as resource, and applications in quantum communication, quantum error correction, and quantum algorithms. Another focus lies on the application and development of machine learning in basic science and on the study of physical models for learning. Some of our work is highly interdisciplinary and addresses questions in different fields including quantum physics, robotics, behavioural biology, and the philosophy of action.

News & Activities

New publication: Quantitative evaluation of methods to analyze motion changes in single-particle experiments
Dr. Muñoz-Gil co-led the 2nd AnDi Challenge, whose results are now published in Nature Communications.

New publication: The (un)detectability of Bohmian trajectories
In this paper, Dr. Fankhauser shows that while pilot‑wave theory assigns definite paths to particles, you can't actually observe them in experiments—apparent “detections” of Bohmian trajectories can all be explained using standard quantum mechanics.

New preprint: Interpretable representation learning of quantum data enabled by probabilistic variational autoencoders
In this preprint, we present the key pieces needed for interpretable ML to extract meaningful information from quantum data, and apply it to extract phase diagrams of simulated and experimental data.

New publication: How many lives does Schrödinger’s cat have?
In this paper, Dr. López-Incera and co-authors present the main concepts in macroscopicity, including macroscopicity measures, experimental realizations and the link to metrology, from a pedagogical perspective. 

New preprint: Synthesis of discrete-continuous quantum circuits with multimodal diffusion models
In this preprint, we extend previous work of the group on quantum circuit generation, enabling now the synthesis of parametrized gates with a novel multimodal diffusion model approach.
