Novel Measurement Tools for Many-Body Experiments
Entanglement certification with quench dynamics;
Phys. Rev. Research 3, L032051 (2021)
As a new generation of quantum hardware realizes hitherto unexplored states of matter, novel detection tools become necessary to actually observe these. For this purpose, quantum setups such as based on cold atoms or trapped ions offer completely new possibilities, e.g., through the ability to manipulate individual particles and to track their dynamical evolution in real time. Exploiting these abilities, we design novel tools for observing and characterizing quantum mechanical states of matter.
