Analog quantum simulators have the potential to provide new insight towards naturally occurring phenomena beyond the capabilities of classical computers in the near term. Incorporating controllable dissipation as a resource enables simulation of a wider range of out-of-equilibrium processes such as chemical reactions. In this talk, I will describe an experiment where we operate a hybrid qubit-oscillator circuit quantum electrodynamics processor and use it to model nonadiabatic molecular reaction dynamics through a so-called conical intersection.

Randomized benchmarking protocols have become the prominent tool for assessing the quality of gates on digital quantum computing platforms.  In `classical' variants of randomized benchmarking multi-qubit gates are drawn uniformly from a finite group.  The functioning of such schemes be rigorous guaranteed under realistic assumptions.  In contrast, experimentally attractive and practically more scalable randomized benchmarking schemes often directly perform random circuits or use other non-uniform probability measures.
