Data re-uploading with a single qudit
Noah L. Wach, Manuel S. Rudolph, Fred Jendrzejewski, and Sebastian Schmitt
arXiv:2302.13932 [quant-ph]Quantum two-level systems, i.e. qubits, form the basis for most quantum machine learning approaches that have been proposed throughout the years. However, in some cases, higher dimensional quantum systems may prove to be advantageous. Here, we …

Probing quantum correlations in many-body systems: a review of scalable methods
Irénée Frérot, Matteo Fadel, and Maciej Lewenstein
arXiv:2302.00640 [quant-ph]We review methods that allow one to detect and characterise quantum correlations in many-body systems, with a special focus on approaches which are scalable. Namely, those applicable to systems with many degrees of freedom, without requiring a number …
