How can one prove that a given quantum state is entangled? In this paper we review
different methods that have been proposed for entanglement detection. We first explain the …

During the past decade the interaction of light with multiatom ensembles has attracted much
attention as a basic building block for quantum information processing and quantum state …

Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

We introduce a general model for a network of quantum sensors, and we use this model to
consider the following question: When can entanglement between the sensors, and/or …

The Fermi-Hubbard model is a key concept in condensed matter physics and provides
crucial insights into electronic and magnetic properties of materials. Yet, the intricate nature …

Distributed quantum sensing uses quantum correlations between multiple sensors to
enhance the measurement of unknown parameters beyond the limits of unentangled …

We show that quantum Fisher information provides a sufficient condition to recognize
multiparticle entanglement in an N qubit state. The same criterion gives a necessary and …

Controlling and measuring the temperature in different devices and platforms that operate in
the quantum regime is, without any doubt, essential for any potential application. In this …

We report the generation of spin squeezing and entanglement in a magnetically sensitive
atomic ensemble, and entanglement-enhanced field measurements with this system. A …

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