摘要：

We demonstrate fast and efficient neutral atom rearrangements in an optical tweezer-trap array, using an enhanced hologram generation algorithm. The conventional Gerchberg-Saxton (GS) algorithm is modified to include zero-padding hologram expansion for optical tweezer sharpness, weighted iteration feedback for reduced crosstalk, and phase induction for successive phase continuity. With the new GS algorithm, we experimentally demonstrate detect-free formation of 2D atom arrays with various geometries, achieving a high loading probability of 0.98 for up to N similar to 30 atoms. Furthermore, the hologram movie calculation speed is enhanced to cover a computational scalability up to O(10(3)).
