Quantum simulation of wave optics in weakly inhomogeneous media using block-encoding
Siavash Davani, Martin Gärttner, Falk Eilenberger
We propose a quantum algorithm that simulates the propagation of a light field through a weakly inhomogeneous medium. In the paraxial approximation, the wave equation in an inhomog…

Area laws and thermalization from classical entropies in a Bose-Einstein condensate
Yannick Deller, Martin Gärttner, Tobias Haas +3
The scaling of local quantum entropies is of utmost interest for characterizing quantum fields, many-body systems, and gravity. Despite their importance, theoretically and experime…
