When level repulsion fails: non-normality and chaos in open quantum systems
Caio B. Naves, Thomas Klein Kvorning, Jonas Larson
For Hamiltonian systems, level statistics provide a faithful diagnostic of quantum chaos. By analogy, the statistics of the Lindbladian spectrum are often used in open quantum syst…
Higher-Dimensional Information Lattice: Quantum State Characterization through Inclusion-Exclusion Local Information
Ian Matthias Flór, Claudia Artiaco, Thomas Klein Kvorning +1
Developing a local description of quantum information is a central problem in quantum many-body physics: the goal is to identify how correlations are organized across positions and…
Witnessing Short- and Long-Range Nonstabilizerness via the Information Lattice
Yuliya Bilinskaya, Miguel F. Martínez, Soumi Ghosh +3
We study nonstabilizerness on the information lattice, and demonstrate that noninteger local information directly indicates nonstabilizerness. For states with a clear separation of…
Efficient Large-Scale Many-Body Quantum Dynamics via Local-Information Time Evolution
Claudia Artiaco, Christoph Fleckenstein, David Aceituno Chávez +2
During time evolution of many-body systems entanglement grows rapidly, limiting exact simulations to small-scale systems or small timescales. Quantum information tends however to f…
Time-evolution of local information: thermalization dynamics of local observables
Thomas Klein Kvorning, Loïc Herviou, Jens H. Bardarson
Quantum many-body dynamics generically results in increasing entanglement that eventually leads to thermalization of local observables. This makes the exact description of the dyna…
