What can we compute with quantum devices?

Quantum computers and simulators promise computational capabilitie that go far beyond those of classical computers. They claim to provide insights into strongly correlated quantum matter that are difficult to come by with classical means. Experimental progress in realizing quantum devices has been rapid in recent years. While this is enormously exciting as such, italso opens up new research questions. So – in what sense can we hope for quantum devices to be able to compute properties beyond classical means? In the technical part of this talk, we will pose variations of this question in three readings.
Firstly, we will witness how efficiently verifiable quantum advantages can be conceived. Secondly, we will look at notions of machine learning that are much in the focus of attention; but to date, most insights in this realm are of a purely heuristic nature. Thus, we will have a look at a rigorous exponential separation of quantum devicesover classical ones in meaningful learning tasks. Thirdly, we will investigate the intricate but simple question of how one can actually ensure that the quantum device has done what it is supposed to do. In each of these themes, we connect to ongoing activities in the Bavarian research landscape.
