Many-Body Quantum Dynamics
The quantum dynamics of many-particle systems is a problem that is notoriously hard to solve numerically on conventional computers. One way of overcoming this challenge, which goes back to Richard Feynman, is to use devices that themselves function based on the laws of quantum mechanics, so called quantum simulators. Recent experimental progress in has let this vision become reality in labs around the world. Our research is centered around the challenges that arise on the way towards using quantum simulation experiments to push the borders of our understanding of many-body physics. One of these challenges is the search for ways in which quantum many-body problems that arise in other research field such as condensed matter and high energy physics can be emulated on quantum simulators. Also these quantum simulation experiments need to be benchmarked or verified by comparing to simulations on conventional computers, for which we develop efficient numerical methods. Finally, the readout, or extraction of the relevant information from the prepared quantum states is often limited due to limited detection capabilities or statistics. To alleviate this problem we develop efficient readout schemes for accessing quantities like unequal-time correlations or entanglement quantifiers. More information on our research can be found here.
Research on quantum simulators requires the close collaboration between experiment and theory. For this, the embedding in the Synthetic Quantum Systems (SynQS) group, consisting of two experimental and two theory groups, provides an ideal environment.

Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's a wonderful problem, because it doesn't look so easy. [Richard P. Feynman]
