Observation of area laws in an interacting quantum field simulator
Maciej T. Jarema, Mohammadamin Tajik, Jörg Schmiedmayer +2
Information shared between parties quantifies their correlation. The encoding of correlations across space and time characterises the structure, history, and interactions of system…
Information and majorization theory for fermionic phase-space distributions
Nicolas J. Cerf, Tobias Haas
We put forward several information-theoretic measures for analyzing the uncertainty of fermionic phase-space distributions using the theory of supernumbers. In contrast to the boso…
Detecting genuine non-Gaussian entanglement
Serge Deside, Tobias Haas, Nicolas J. Cerf
Efficiently certifying non-Gaussian entanglement in continuous-variable quantum systems is a central challenge for advancing quantum information processing, photonic quantum comput…
Quantum Gravity, Hydrodynamics and Emergent Cosmology: A Collection of Perspectives
Jibril Ben Achour, Dario Benedetti, Martin Bojowald +17
This collection of perspective pieces captures recent advancements and reflections from a dynamic research community dedicated to bridging quantum gravity, hydrodynamics, and emerg…
From bosons and fermions to spins: A multi-mode extension of the Jordan-Schwinger map
Benoît Dubus, Tobias Haas, Nicolas J. Cerf
The Jordan-Schwinger map is widely employed to switch between bosonic or fermionic mode operators and spin observables, with numerous applications ranging from quantum field theori…
