Welcome to the website of the Quantum Randomness and Complexity Group at the University of Cologne. 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 quantum circuits, in particular of shallow depth. We are combining these insights with tensor networks to develop efficient and scalable algorithms and protocols. For more details on our research, click here.
