Exploring spin chain dynamics with superconducting transmon qubits*

In this talk, we discuss probing the scrambling of information in many-body systems using superconducting transmon qubit-based IBM quantum hardware. Particular interest will be given to the spread of correlations or "light-cones" in one-dimensional spin chain systems. For concreteness, we start with the simple, but rich, physics afforded by the transverse-field Ising model and discuss the initial state dependence of the light-cone velocity. We then highlight our efforts to realize the disordered XXZ chain and PXP model which can exhibit the phenomena of many-body localization and many-body scarring respectively. We conclude by discussing the progress and future outlook in observing such diverse spin chain dynamics using IBM quantum hardware.
