Optimally driving multi-photon transitions in the perturbative single-mode regime
Frieder Lindel, Stefan Yoshi Buhmann, Andreas Buchleitner +1
The rate of -photon transitions in matter, induced by an incident light field, depends on the field's th order coherence function. Consequently, the coherence properties of t…
Many-body interference at the onset of chaos
Eric Brunner, Lukas Pausch, Edoardo G. Carnio +3
We unveil the signature of many-body interference across dynamical regimes of the Bose-Hubbard model. Increasing the particles' indistinguishability enhances the temporal fluctuati…
How to seed ergodic dynamics of interacting bosons under conditions of many-body quantum chaos
Lukas Pausch, Edoardo G. Carnio, Andreas Buchleitner +1
We demonstrate how the initial state of ultracold atoms in an optical lattice controls the emergence of ergodic dynamics as the underlying spectral structure is tuned into the quan…
Entanglement structures in disordered chains of nitrogen-vacancy centers
Alexander M. Minke, Andreas Buchleitner, Edoardo G. Carnio
A recent study [Phys. Rev. B 17 174111 (2022)] has hypothesized the assembly, along a specific type of one-dimensional defects of diamond, of chains of nitrogen-vacancy (NV) center…
Machine-learning certification of multipartite entanglement for noisy quantum hardware
Andreas J. C. Fuchs, Eric Brunner, Jiheon Seong +5
Entanglement is a fundamental aspect of quantum physics, both conceptually and for its many applications. Classifying an arbitrary multipartite state as entangled or separable -- a…
