Entanglement detection in quantum many-body systems using entropic uncertainty relations
Bjarne Bergh, Martin Gärttner
We study experimentally accessible lower bounds on entanglement measures based on entropic uncertainty relations. Experimentally quantifying entanglement is highly desired for appl…
Experimentally accessible bounds on distillable entanglement from entropic uncertainty relations
Bjarne Bergh, Martin Gärttner
Entanglement is not only the resource that fuels many quantum technologies but also plays a key role for some of the most profound open questions of fundamental physics. Experiment…
Neural network quantum state tomography in a two-qubit experiment
Marcel Neugebauer, Laurin Fischer, Alexander Jäger +4
We study the performance of efficient quantum state tomography methods based on neural network quantum states using measured data from a two-photon experiment. Machine learning ins…
Classical and quantum chaos in a three-mode bosonic system
Michael Rautenberg, Martin Gärttner
We study the dynamics of a three-mode bosonic system with mode-changing interactions. For large mode occupations the short-time dynamics is well described by classical mean-field e…
Bang-bang shortcut to adiabaticity in the Dicke model as realized in a Penning trap experiment
J. Cohn, A. Safavi-Naini, R. J. Lewis-Swan +7
We introduce a bang-bang shortcut to adiabaticity for the Dicke model, which we implement via a 2-D array of trapped ions in a Penning trap with a spin-dependent force detuned clos…
Verification of a many-ion simulator of the Dicke model through slow quenches across a phase transition
A. Safavi-Naini, R. J. Lewis-Swan, J. G. Bohnet +7
We use a self-assembled two-dimensional Coulomb crystal of ions in the presence of an external transverse field to engineer a simulator of the Dicke Hamiltonian, an iconi…
