Experiment data for "Observation of critical phase transtition in a generalized AAH model with superconducting qubits"

We simulated the one-dimensional generalized Aubry-Andre-Harper model for extended, localized and critical phases by using a programmable quantum processor with 10 superconducting qubits interacted through tunable couplers. We studied the properties of phase transitions and many-body dynamics in the presence of quasi-periodic modulations for both off-diagonal hopping coefficients and on-site potentials of the model controlled respectively by adjusting strength of couplings and qubit frequencies. We observed the spin transport for initial single- and multi-excitation states in different phases, and characterize phase transitions by experimentally measuring dynamics of participation entropies.
