Exploring noise robust phases of quantum matter

ORAL · Invited

Abstract

The threshold theorem in quantum computing guarantees that it is possible to perform reliable computation with a provable advantage over classical computers. Experimental progress in quantum devices has advanced this concept from a theoretical curiosity to one of increasing technological relevance. These developments inspire new questions at the intersection of many-body physics and computer science about how to characterize, describe, and exploit dynamical phases of quantum matter that arise in fault-tolerant quantum computers. In this talk, I will describe several examples in this direction from my research, illustrated also by experiments on current quantum devices.
