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 speeds and limited loading fidelities of stochastic preparation methods.
To overcome these limitations, in this work we introduce a dissipative scheme for loading atoms into tweezers, mediated by laser-coupled interactions with a fermionic bath. In particular, we explore the tradeoff between loading time and fidelity depending on the strength of the system bath coupling and the impact of reservoir size and temperature.
