Fig. 3: Subdiffusive transport on the superconducting qubit ladder with disorder.
From: Probing spin hydrodynamics on a superconducting quantum simulator
a The time evolution of autocorrelation function C1,1(t) for the qubit ladder with L = 12 and different values of disorder strength W, ranging from W/2π = 35 MHz (\(W/\overline{{J}^{\parallel }}\simeq 0.5\)) to W/2π = 70 MHz (\(W/\overline{{J}^{\parallel }}\simeq 9.6\)). Markers (lines) are experimental (numerical) data. b Transport exponent α as a function of W obtained from fitting the data of C1,1(t). Error bars (experimental data) and shaded regions (numerical data) represent the standard deviation.
