Near-deterministic loading of optical tweezer arrays via repulsive barricade potentials

Alex J. Matthies, Archie C. Baldock, Hannah J. Williams, Luke Caldwell

Repulsive barricade potentials protect particles in optical tweezers to enable multiple loading cycles and reach 94 percent success for atoms.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We show that collision-limited lifetimes of particles in protected tweezers can reach hundreds of milliseconds, allowing loading probabilities of 82% for molecules and 94% for atoms after four loading cycles.

C2weakest assumption

The repulsive barricade can be implemented without disrupting the primary trapping potential or the ability to load new particles into empty sites, and that the assumed collision rates permit the stated lifetimes.

C3one line summary

Repulsive barricade potentials enable multiple loading cycles in optical tweezers by extending collision-limited lifetimes to hundreds of milliseconds, achieving 94% atom and 82% molecule loading after four cycles.
