Superoperators vs. Trajectories for Matrix Product State Simulations of Open Quantum System: A Case Study
Lars Bonnes, Andreas M. Läuchli
Quantum trajectories and superoperator algorithms implemented within the matrix product state (MPS) framework are powerful tools to simulate the real-time dynamics of open dissipat…
Probing Entanglement in Adiabatic Quantum Optimization with Trapped Ions
Philipp Hauke, Lars Bonnes, Markus Heyl +1
Adiabatic quantum optimization has been proposed as a route to solve NP-complete problems, with a possible quantum speedup compared to classical algorithms. However, the precise ro…
Dynamical and Steady State Properties of a Bose-Hubbard Chain with Bond-Dissipation: A Study based on Matrix Product Operators
Lars Bonnes, Daniel Charrier, Andreas M. Läuchli
We study a dissipative Bose-Hubbard chain subject to an engineered bath using a superoperator approach based on matrix product operators. The dissipation is engineered to stabilize…
"Light-cone" dynamics after quantum quenches in spin chains
Lars Bonnes, Fabian H. L. Essler, Andreas M. Läuchli
Signal propagation in the non equilibirum evolution after quantum quenches has recently attracted much experimental and theoretical interest. A key question arising in this context…
