Scientific work edit
He is known for his research in quantum information science and quantum many-body theory in condensed matter physics. He has made significant contributions to entanglement theory and the study of quantum computing, as well as to the development of protocols in the quantum technologies and to the study of complex quantum systems. Work on compressed sensing quantum state tomography[1] he has contributed to has been influential for developing notions of benchmarking and the verification of quantum devices to ensure their proper functioning.[2] The concept of a graph state[3] has become a relevant class of multi-qubit quantum states with a number of applications in quantum computing.
He has contributed to realizing a first dynamical quantum simulator,[4] in joint work with Immanuel Bloch, Ulrich Schollwöck and others, building on his work on non-equilibrium quantum physics.[5][6] This work has also introduced the idea of benchmarking the performance of quantum devices against that of state-of-the-art classical tensor network methods for classical simulation, an idea that is still much pursued in the quest for achieving a quantum advantage[7] or quantum supremacy, as the situation of quantum devices computationally outperforming classical devices is also referred to.
In quantum many-body theory, he has helped understanding the role of area laws for entanglement entropies in quantum physics that are at the root of the functioning of tensor network methods.[8] He is also notable as one of the co-pioneers of quantum game theory[9][10] with Maciej Lewenstein and PhD advisor Martin Wilkens.
Education edit
He attended high school at the Wilhelm von Humboldt Gymnasium, Ludwigshafen, Germany. He obtained his first degree in physics from the University of Freiburg and his master's degree in mathematics and physics from the University of Connecticut under a Fulbright scholarship. In 2001, he obtained his PhD from University of Potsdam under Martin Wilkens with a thesis entitled Entanglement in Quantum Information Theory.
Career edit
In 2001–2002, he was a Feodor Lynen Fellow at Imperial College London. In 2002–2003, he was a visiting scholar at Caltech. During 2002–2005, he was a junior professor at the University of Potsdam. During the 2005–2008 period he was a lecturer at Imperial College London. In 2008, he became a full professor at the University of Potsdam and in 2011 a full professor at the Free University of Berlin. In 2009–2010, he was a fellow at the Institute for Advanced Study, Berlin.
He is a divisional associate editor of the Physical Review Letters.[11] He is also known for consistent contributions to the scientific community, such as being a coauthor of the European quantum technologies roadmap.[12]
