Geometric speed limit of state preparation and curved control spaces
Maximilian Goll, Robert H. Jonsson
The preparation of quantum many-body systems faces the difficulty that in a realistic scenario only few control parameters of the system may be accessible. In this context, an inte…

Non-Exponential Decay in Finite Photonic Waveguide Arrays
Florian H. Huber, Benedikt Braumandl, Johannes Knörzer +5
Open quantum-system dynamics can follow exponential decay, non-exponential relaxation, or oscillatory dynamics, depending on the system-environment coupling. We study a lattice wit…
