The Institute for Quantum Information (IQI) unites the theory groups of Prof. Mario Berta, Prof. Fabian Hassler, and Prof. Markus Müller. Working at the intersection of physics, computer science, and mathematics, the groups investigate the full spectrum of quantum‑information science.
Their research ranges from information theory, cryptography and quantum algorithms to the mathematical structure of quantum states, as well as to concrete physical platforms such as topological states of matter, non‑Abelian anyons, superconducting qubits, neutral atoms, and ion traps. A central ambition of the institute is to develop scalable, fault‑tolerant quantum technologies and practical architectures for quantum computing.
Mission
Founded in 2011 as one of Germany’s first institutes dedicated to quantum‑information theory, IQI focuses on the conceptual side of the field. We study how quantum information reshapes our understanding of quantum mechanics—revealing new perspectives on entanglement, uncertainty, and the structure of quantum states. By exploring the mathematical foundations of quantum algorithms, error correction, quantum optics and topological models, we aim to deepen the theoretical framework of the discipline.
Quantum Technology Group
The Institute for Quantum Information at RWTH Aachen University maintains a close collaboration with the experimental Quantum Technology Group. Together, we bridge theoretical quantum information research and cutting-edge experimental implementations, fostering strong exchange between theory and experiment.
