Quantum information theory in Berlin

We investigate the fundamental principles of quantum information processing and complex quantum many-body systems. Using methods from mathematical physics, quantum information theory and computational science, we seek a deeper understanding of quantum phenomena while addressing the fundamental challenges underlying emerging quantum technologies. Our research spans quantum computing, quantum error correction, quantum algorithms, quantum communication and the study of strongly correlated quantum matter.

Quantum Information Systems Beyond Classical Capabilities / Special Research Programme

After two decades of intensive experimental and theoretical research in quantum science, we have now reached a new era of quantum technologies. Several scenarios have been identified for which quantum information processing outperforms its classical analogue. Moreover, various implementations have demonstrated reliable control and operation of around ten qubits. Despite these efforts and advances, we are still very far away from a full-fledged quantum device mastering several thousand qubits.

Quantum Randomness Group, U Cologne (GER)

We are interested in a wide range of topics in quantum information and quantum computing connected to understanding the power and limitations of near-term quantum devices. As a major tool, we are using random quantum circuits to better understand the generic expressitivity of short quantum circuits.
Research focus:
- random unitaries and designs
- quantum learning theory
- quantum computing resources
- benchmarking and characterization
- classical simulation
