The ability to manipulate quantum states of light by integrated devices may open new
perspectives both for fundamental tests of quantum mechanics and for novel technological …

The concept of randomized measurements on individual particles has proven to be useful
for analyzing quantum systems and is central for methods like shadow tomography of …

We show that the rich structure of multipartite entanglement can be tested following a device-
independent approach. Specifically we present Bell inequalities for distinguishing between …

Going beyond the standard quantum limit in noisy quantum metrology is an important and
challenging task. Here we show how Dicke states can be used to surpass the standard …

Quantum mechanics is a nonlocal theory, but not as nonlocal as the no-signalling principle
allows. However, there exist quantum correlations that exhibit maximal nonlocality: they are …

Dicke states are typical examples of quantum states with genuine multipartite entanglement.
They are valuable resources in many quantum information processing tasks, including …

We report the experimental demonstration of two quantum networking protocols, namely
quantum<? format?> 1→ 3 telecloning and open-destination teleportation, implemented …

Quantum states that are symmetric with respect to permutations of their subsystems appear
in a wide range of physical settings, and they have a variety of promising applications in …

We consider different classes of quenched disordered quantum XY spin chains, including a
quantum XY spin glass and a quantum XY model with a random transverse field, and …

We show how the entanglement contained in states of spins arranged on a lattice may be
lower bounded with observables arising in scattering experiments. We focus on the partial …
