Universal Uhrig dynamical decoupling for bosonic systems
Margret Heinze, Robert Koenig
We construct efficient deterministic dynamical decoupling schemes protecting continuous variable degrees of freedom. Our schemes target decoherence induced by quadratic system-bath…

Approximation algorithms for quantum many-body problems
Sergey Bravyi, David Gosset, Robert Koenig +1
We discuss classical algorithms for approximating the largest eigenvalue of quantum spin and fermionic Hamiltonians based on semidefinite programming relaxation methods. First, we…

Continuum limits of homogeneous binary trees and the Thompson group
Alexander Kliesch, Robert Koenig
Tree tensor network descriptions of critical quantum spin chains are empirically known to reproduce correlation functions matching CFT predictions in the continuum limit. It is nat…
