  1. Feb 14, 2024The quantum mechanics formalism introduced new revolutionary concepts challenging our everyday perceptions. Arguably, quantum entanglement, which explains correlations that cannot be reproduced classically, is the most notable of them. Besides its fundamental aspect, entanglement is also a resource, fueling emergent technologies such as quantum simulators and computers. The purpose of this ...

    For this reason, the certification of such a feature is a necessary first step to assess the presumed advantage such devices may provide. The remainder of the subsection will be devoted to the detection of many-body quantum entanglement and Bell correlation. 4.4.2.1 Detecting Many-Body Entanglement in Rotation-Invariant States

  4. While many entanglement reviews have already been written, the majority of them are from more than 15 years ago (cf. Amico2008 ; Horodecki_2009 ).To address this aspect, we provide a review with an easy and didactic introduction to the topic, and at the same time, we discuss some of the newest results in the field.

  7. the concepts above to investigate the phase diagram of a spin-1 chain. 2 Many-body entanglement In the following, we introduce the concept of entanglement entropy and entanglement spectra in many-body systems. Let us consider the bipartition of the Hilbert space H= H A H B of an N-body quantum system as illustrated in Fig. 1(a), where H A(H
  8. The recent interest in aspects common to quantum information and condensed matter has prompted a prosperous activity at the border of these disciplines that were far distant until few years ago. Numerous interesting questions have been addressed so far. Here we review an important part of this field, the properties of the entanglement in many-body systems. We discuss the zero and finite ...

    In a significant stride forward, PASQuanS2.1 partners from Universität Innsbruck have recently disseminated noteworthy findings in Nature. The Innsbruck team, led by Peter Zoller, has experimentally demonstrated an innovative approach poised to significantly expedite the characterization of large-scale entanglement in quantum many-body systems.

The purpose of this chapter is to give a pedagogical introduction to the topic with a special emphasis on the multipartite scenario, i.e., entanglement distributed among many degrees of freedom. Due to the combinatorial complexity of this setting, particles can interact ...

    Lecture "Entanglement in quantum many-body systems" (summer term 2021) Lecturer: Norbert Schuch ufind: 260070-1 VU Entanglement in quantum many-body systems (2021S) Overview. Correlated quantum many-body systems are systems composed of many particles (such as materials) where at low temperatures, complex quantum correlations ("entanglement") between the individual constituents play a central role.
