I will describe the challenges on the way to a scalable, eventually fault tolerant quantum computers [1]. Efforts from physics, informatics [2,3] & mathematics but also engineering [4] are concentrated in demonstrator setups. As a first glance into the power of quantum computing, I will describe a couple of use cases: the VQE-simulation of a two-flavor Schwinger quark model executed on a trapped-ion quantum processor [5], and the quantum autoencoder [6], as a simple instance of machine learning on this hardware. Using, and extending the toolset of quantum computing we are investigating circuits that realize quantum thermodynamic- [7,8,9] and quantum communication processes [10].
