Abstract:

There is a hope that scaled fault-tolerant quantum computers will revolutionize our understanding of the strongly coupled quantum systems encountered in both condensed matter and high energy. The advent of intermediate-scale quantum processors has led to a remarkable exchange in the opposite direction: abstract ideas originating from the study of low-dimensional quantum field theory directly inform the practical design and near-term utilization of these devices. We describe three simple examples of this phenomenon that have already been realized, all arising from aspects of 2+1D discrete gauge theory: non-Abelian exchange statistics as a path to fault-tolerant gates, probing disordered systems by embedding into background charge sectors, and accessing string dynamics in a 2D confining phase.
