Quantum simulation - Engineering & understanding quantum systems atom- by-atom — •Monika Aidelsburger — Fakultät für Physik, Ludwig-Maximilians-Universität München — Munich Center for Quantum Science and Technology (MCQST), 80799 Munich, Germany

The computational resources required to describe the full state of a quantum many-body system scale exponentially with the number of constituents. This severely limits our ability to explore and understand the fascinating phenomena of quantum systems using classical algorithms. Quantum simulation offers a potential route to overcome these limitations. The idea is to build a well-controlled quantum system in the lab, which represents the problem of interest and whose properties can be studied by performing measurements. In this talk I will introduce quantum simulators based on neutral atoms that are confined in optical arrays using laser beams. State-of-the-art experiments now reach several thousand particles, while maintaining control on the level of single atoms. I will show how these systems are realized and how they can be used to study topological phases of matter. In the end I will provide a brief outlook on new directions in the field based on optical tweezers and the unique properties of alkaline-earth(-like) atoms.
