Polymer-Electrolyte-Membrane (PEM) fuel cell systems will contribute to enable climate-neutral mobility through the chemical reaction of hydrogen and oxygen. PEM fuel cells address applications which are hardly decarbonized ...

We present a scalable method for the tomography of large multiqubit quantum registers. It acquires information about the permutationally invariant part of the density operator, which is a good approximation to the true ...

Large-eddy simulation (LES) has become a well-established tool in the atmospheric boundary-layer research community to study turbulence. It allows three-dimensional realizations of the turbulent fields, which large-scale ...
