In this talk, we study the propagation, entanglement, and entropy of quantum information using 3x3 and 4x4 arrays of superconducting qubits that emulate the two-dimensional (2D) hard-core Bose-Hubbard model. The 2D arrays feature site-selective, simultaneous control and readout of all qubits. We highlight several recent experimental demonstrations using these arrays, including quantum random walks, Anderson and Wannier-Stark localization [1], the crossover from area-law to volume-law entanglement [2], the realization of synthetic electromagnetic fields throughout the array [3], and studies of flat-band physics in rhombic lattices [4].
