DESCRIPTION:Titel: Understanding\, controlling and creating many-body 
 systems atom by atom Abstract: Microscopic control and readout of indi
 vidual quanta has been one of the driving forces behind advances in qu
 antum science and technology in recent years\, leading to spectacular 
 breakthroughs across quantum simulation\, quantum computing\, quantum 
 optics\, and quantum metrology. In my talk\, I will present recent res
 ults on quantum-gas microscopy of many-body systems both in and out of
  equilibrium. In particular\, I will discuss an experiment demonstrati
 ng strongly constrained out-of-equilibrium transport and the emergence
  of Hilbert space fragmentation in two-dimensional tilted Hubbard syst
 ems. In the second part of my talk\, I will introduce a hybrid experim
 ental platform based on the alkaline-earth atom strontium. By directly
  loading thousands of individually addressable atoms from a magneto-op
 tical trap into an optical lattice\, we achieve high-fidelity\, low-lo
 ss imaging and iterative assembly of atom arrays. For applications in 
 quantum computing and simulation\, we encode a qubit in the metastable
  fine-structure states of strontium\, demonstrating long coherence tim
 es\, high-fidelity control\, and fast initialization via coherent thre
 e-photon coupling from the ground state. I will conclude by outlining 
 our ongoing work on a new experimental platform that integrates an opt
 ical resonator with tweezer-trapped atoms\, enabling novel light-matte
 r interfaces for quantum simulators and quantum computers. Sprecher /
