Classical electronic circuits have proven powerful to study topological lattice structures. At the same time quantum simulators reach for increasingly complex lattice gauge theories with the goal of simulating processes in high energy physics. This …
This thesis presents a setup capable of creating arbitrary potentials for a two-dimensional Bose-Einstein condensate. A Digital Micromirror Device is used to spatially modulate and thus shape a laser beam. Reimaged to the position of the atomic …
Far from equilibrium, comparatively little is known about the possibilities nature reserves for the structure and states of quantum many-body systems. A potential scenario is that these systems can approach a non-thermal fixed point and show …
This thesis reports on the experimental realization of an elementary building block for analog quantum simulation of a U(1) lattice gauge theory in a mixture of two bosonic quantum gases. Experimentally, the building block is realized by …
The aim of this work is to explore practical implementations of Quantum and Quantum-assisted Machine Learning algorithms and benchmark potential benefits of utilizing quantum phenomena in Quantum-assisted Neural Networks with qubit layers. Two known …
In atomic physics experiments, setting the magnetic field strength allows one to create spin dynamics between atoms, or to tune the interaction between them. This makes stable magnetic fields desirable, but unfortunately no commercially available …
Approximate simulation methods of quantum many-body systems play an important role for better understanding quantum mechanical phenomena, since due to the exponentially scaling Hilbert space dimension these systems cannot be treated exactly. However, …
Studying the entanglement among many particles is a central topic of current research in quantum many-body systems and has great importance to the field of quantum metrology. In this context, the quantum Fisher information (QFI) provides a powerful …
