Information is encoded in physical systems. Hence, information theory and physics are intimately linked. To understand the capabilities and limitations of information theory, one must consider the fundamental principles of nature that describe how physical systems work and interact. These fundamental principles are ultimately described by quantum physics and general relativity.
In the Quantum Physics of Information (QPI) group, we specialize in quantum information theory and its applications. We investigate the foundations of quantum mechanics and quantum information, specifically Bell nonlocality, entanglement, and quantum contextuality. We explore how recently developed tools in quantum information theory can help elucidate fundamental problems in quantum field theory. We contribute to different sub-areas of quantum information, such as quantum computing (quantum algorithms for graph problems), quantum thermodynamics and quantum machine learning. Furthermore, we develop quantum networking (quantum routing, error correction and purification) protocols and quantum cryptographic systems using quantum optics, and optical quantum memories based on atomic gases. The experimental research is performed in the Quantum Photonics Laboratory (QuLab).
