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.
