Bell's theorem proves that quantum theory is inconsistent with local physical models. It has
propelled research in the foundations of quantum theory and quantum information science …

Bell's 1964 theorem, which states that the predictions of quantum theory cannot be
accounted for by any local theory, represents one of the most profound developments in the …

The ability to control multidimensional quantum systems is central to the development of
advanced quantum technologies. We demonstrate a multidimensional integrated quantum …

A bstract A rather general method for determining the spin density matrix of a multi-particle
system from angular decay data is presented. The method is based on a Bloch …

A bstract Pair production of heavy vector bosons is a key process at colliders: it allows to test
our understanding of the Standard Model and to explore the existence of new physics …

The orbital angular momentum of light represents a fundamentally new optical degree of
freedom. Unlike linear momentum, or spin angular momentum, which is associated with the …

We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

We are interested in the problem of characterizing the correlations that arise when
performing local measurements on separate quantum systems. In a previous work …

We discuss quantum entanglement and violation of Bell inequalities in the H→ ZZ decay, in
particular when the two Z-bosons decay into light leptons. Although such process implies an …

We introduce a hierarchy of conditions necessarily satisfied by any distribution P α β
representing the probabilities for two separate observers to obtain outcomes α and β when …
