Quantum simulation and quantum computing with ultracold atoms. – (Immanuel BLOCH / Seminar/ SFP). – 4/07/2025, 11H

Séminaire SFP

Immanuel BLOCH, Max-Planck Institute of Quantum Optics de Munich, Salle de conférence, Bat. 3R4

Summary:
Quantum simulation has become a powerful interdisciplinary tool for probing quantum matter with microscopic resolution, both in and out of equilibrium. Platforms based on ultracold atoms in optical lattices and tweezers have played a crucial role in the development of the field, with applications ranging from strongly correlated electronic or spin systems, the investigation of out-of-equilibrium dynamics to novel quantum optical light matter interfaces. These systems offer complementary insights to those obtained from advanced numerical methods. In particular, fermionic quantum simulators have begun to reveal new aspects of strongly interacting regimes that challenge conventional computational approaches

Alongside analog approaches, gate-based quantum computing offers broader universality, though it remains limited by scalability and error correction demands. Hybrid strategies combining both paradigms may offer a promising route to address complex quantum many-body problems in the near term. This talk will survey recent progress, highlight key challenges, and discuss future directions at the interface of quantum simulation,computation, and many-body physics.
