Revealing entanglement through local features of phase-space distributions
Elena Callus, Martin Gärttner, Tobias Haas
We formulate an infinite hierarchy of continuous-variable separability criteria in terms of quasiprobability distributions and their derivatives evaluated at individual points in p…
Configurable photonic simulator for quantum field dynamics
Mauro D'Achille, Martin Gärttner, Tobias Haas
Quantum field simulators provide unique opportunities for investigating the dynamics of quantum fields through tabletop experiments. A primary drawback of standard encoding schemes…
Interferometric detection of continuous-variable entanglement using two states
Elena Callus, Martin Gärttner, Tobias Haas
The efficient witnessing and certification of entanglement is necessitated by its ubiquitous use in various aspects of quantum technologies. In the case of continuous-variable bipa…
Area laws from classical entropies
Tobias Haas
The area law-like scaling of local quantum entropies is the central characteristic of the entanglement inherent in quantum fields, many-body systems, and spacetime. Whilst the area…
Entropy estimation in a spin-1 Bose-Einstein condensate
Yannick Deller, Martin Gärttner, Tobias Haas +3
We investigate the information extractable from measurement distributions of two non-commuting spin observables in a multi-well spin-1 Bose-Einstein condensate. We provide a variet…
Area laws and thermalization from classical entropies in a Bose-Einstein condensate
Yannick Deller, Martin Gärttner, Tobias Haas +3
The scaling of local quantum entropies is of utmost interest for characterizing quantum fields, many-body systems, and gravity. Despite their importance, theoretically and experime…
