Summary: In this study, we use an optical tweezer array with lithium-6 atoms to create an eight-site Fermi-Hubbard chain near half filling. By combining the tweezer array with a quantum gas microscope, we are able to detect individual sites. By minimizing disorder in energy offsets, we observe Mott insulators with strong antiferromagnetic correlations and measure the spin correlations, which lead us to estimate an upper bound of entropy per atom. We also demonstrate the flexibility of the tweezer platform by initializing atoms on one tweezer and observing tunneling dynamics across the array for different geometries.

Summary: Quantum walks provide an intuitive and universal framework for designing quantum algorithms, allowing programmable modification of the walker's graph while maintaining coherence. In this study, we combine the control of optical tweezers with the environment of an optical lattice to investigate continuous-time quantum walks of single atoms on a square lattice and demonstrate spatial search. These capabilities can be extended to study various problems in quantum information science, including more effective spatial search using larger, more connected graphs.
