a. An illustration of the atom distribution of the prepared unity-filled Mott insulator state after staggered immersion cooling. Atoms in orange-shaded chains are then addressed by DMD light. b. An illustration of the atomic spin distribution after the site-dependent addressing. c. An illustration of the state after we merge every two atoms in \(\left\vert \downarrow \right\rangle\) state onto a single site along the y direction. d. The prepared copies of \(\left\vert 2020112020\right\rangle\) state along the y direction.
