Abstract: Experimental progress in quantum computing has yielded exciting new tools for probing and manipulating superconducting circuits. I will present our recent work on driven behavior of 1D and 2D Josephson junction arrays. In one dimension, we have recently studied the lifetime and dynamics of plasmons, which makes some interesting connections to the physics of one-dimensional quantum liquids and classical nonlinear systems. In two dimensions, I will show our discovery of non-equilibrium microwave radiation and non-equilibrium noise scaling near the superconductor-insulator quantum phase transition.
