Computing complexity measures for quantum states based on exponential families
Sönke Niekamp, Tobias Galla, Matthias Kleinmann +1
Given a multiparticle quantum state, one may ask whether it can be represented as a thermal state of some Hamiltonian with k-particle interactions only. The distance from the expon…

Increasing the statistical significance of entanglement detection in experiments
Bastian Jungnitsch, Sönke Niekamp, Matthias Kleinmann +6
Entanglement is often verified by a violation of an inequality like a Bell inequality or an entanglement witness. Considerable effort has been devoted to the optimization of such i…
