Environmental effects in quantum annealing
Tobias Chasseur, Stefan Kehrein, Frank K. Wilhelm
For quantum annealing, as opposed to circuit based quantum computing, the solution to a computational problem is encoded in the ground state of a quantum system. Therefore its susc…
Tripartite information, scrambling, and the role of Hilbert space partitioning in quantum lattice models
Oskar Schnaack, Niklas Bölter, Sebastian Paeckel +3
For the characterization of the dynamics in quantum many-body systems the question how information spreads and becomes distributed over the constituent degrees of freedom is of fun…
Exact description of the boundary theory of the Kitaev Toric Code with open boundary conditions
Yevheniia Cheipesh, Lorenzo Cevolani, Stefan Kehrein
In this work we consider the Kitaev Toric Code with specific open boundary conditions. Such a physical system has a highly degenerate ground state determined by the degrees of free…
Semiclassical echo dynamics in the Sachdev-Ye-Kitaev model
Markus Schmitt, Dries Sels, Stefan Kehrein +1
The existence of a quantum butterfly effect in the form of exponential sensitivity to small perturbations has been under debate for a long time. Lately, this question gained increa…
