Dissipative loading of ultracold atom tweezer arrays — •Lara Giebeler1, Alexander Schnell1, Monika Aidelsburger2,3,4, and André Eckardt11Institute for Physics and Astronomy, Technical University Berlin — 2Munich Center for Quantum Science and Technology — 3Max-Planck-Institut für Quantenoptik — 4Fakultät für Physik, LMU Munich

Using ultracold atoms in quantum computing and simulation often requires arbitrary single-atom control, typically achieved with optical tweezer arrays. However, defect-free loading of large-scale arrays remains challenging due to the slow speed of adiabatic preparation methods.

To overcome these limitations, in this work we introduce a dissipative scheme for loading fermionic atoms into tweezers, mediated by lasercoupled interactions with a fermionic bath. In particular, we explore the trade-off between loading time and efficiency depending on the system bath coupling and the impact of reservoir size and temperature.
