Light-cone and diffusive propagation of correlations in a many-body dissipative system
Jean-Sebastien Bernier, Ryan Tan, Lars Bonnes +3
We analyze the propagation of correlations after a sudden interaction change in a strongly interacting quantum system in contact with an environment. In particular, we consider an…
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…
Entanglement Spectroscopy using Quantum Monte Carlo
Chia-Min Chung, Lars Bonnes, Pochung Chen +1
We present a numerical scheme to reconstruct a subset of the entanglement spectrum of quantum many body systems using quantum Monte Carlo. The approach builds on the replica trick…
Thermal vs. Entanglement Entropy: A Measurement Protocol for Fermionic Atoms with a Quantum Gas Microscope
Hannes Pichler, Lars Bonnes, Andrew J. Daley +2
We show how to measure the order-two Renyi entropy of many-body states of spinful fermionic atoms in an optical lattice in equilibrium and non-equilibrium situations. The proposed…
