Query: Efficient two-dimensional defect-free dual-species atom arrays
  rearrangement algorithm with near-fewest atom moves   Dual-species atoms in optical tweezer arrays have shown several advantages
over the single-species atoms array as a platform for quantum science. Hence,
designing an efficient algorithm to rearrange the stochastically loaded
dual-species atoms arrays into arbitrary demanded configuration is crucial.
Here we proposed a heuristic algorithm [the heuristic connectivity optimization
algorithm (HCOA)] which provides the near-fewest number of atom moves $M\approx
M_{min}$ ($M_{min}$ is the ideal number of atom moves supposing all atoms can
be moved freely). Moreover, our algorithm shows high success rate ($>97\%$ for
intermediate array size ($<500$), 0.5 initial filling ratio, and various
configurations), low extra atom moves ratio ($M_m/M-1\approx6\%$ for
10$\times$10 atom array, good scalability (the success rate remains at high
level with the array size increasing, and the extra atom moves ratio decays as
the array size increases), and versatility (our algorithm can be applied in
various array types, e.g. honeycomb lattice, irregular lattice and so on).
Besides, we also proposed a complementary step to solve almost all cases left
unsolved by HCOA and atom loss in experiment.
