The many-body physics at quantum phase transitions shows a subtle interplay between
quantum and thermal fluctuations, emerging in the low-temperature limit. In this review, we …

Quantum information theory has considerably helped in the understanding of quantum many-
body systems. The role of quantum correlations and in particular, bipartite entanglement …

Many quantum algorithms have daunting resource requirements when compared to what is
available today. To address this discrepancy, a quantum-classical hybrid optimization …

Two topics, evolving rapidly in separate fields, were combined recently: the out-of-time-
ordered correlator (OTOC) signals quantum-information scrambling in many-body systems …

External monitoring of quantum many-body systems can give rise to a measurement-
induced phase transition characterized by a change in behavior of the entanglement entropy …

We witness multipartite entanglement in the ground state of the Kitaev chain—a benchmark
model of a one dimensional topological superconductor—also with variable-range pairing …

Several tasks in quantum-information processing involve quantum learning. For example,
quantum sensing, quantum machine learning, and quantum-computer calibration involve …

We study the ground state properties of the one-dimensional extended Hubbard model at
half filling from the perspective of its particle reduced density matrix. We focus on the …

The interplay of quantum and thermal fluctuations in the vicinity of a quantum critical point
characterizes the physics of strongly correlated systems. Here we investigate this interplay …

Entanglement comes in different forms, some more complex than others. In this paper we
study the transitions of entanglement complexity in an exemplary family of states—the …
