Event Details & Abstract: 

The quantum toolbox of the Innsbruck ion-trap quantum computer is applied to perform (analog) quantum simulations of the dynamics and the propagation of entanglement in a quantum many-body system represented by long chains of trapped-ion qubits. A spectroscopic technique is presented to study artificial quantum matter and use it for characterizing quasiparticles in a many-body system of trapped atomic ions. Furthermore, it will be shown how strings of trapped ions can be used for (digital) quantum simulations of a lattice gauge field theory. As an example, we map the real-time evolution of the Schwinger mechanism to a string of trapped ions in a few-qubit quantum computer, simulating the spontaneous creation of electron-positron pairs.
