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…

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…

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…

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…

An Energy Estimation Benchmark for Quantum Computers

Andreas J. C. Woitzik, Lukas Hoffmann, Andreas Buchleitner +1

Certifying the performance of quantum computers requires standardized tests. We propose a simple energy estimation benchmark that is motivated from quantum chemistry. With this ben…

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…
