All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

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 …

Quantum information theory is a branch of science at the frontier of physics, mathematics,
and information science, and offers a variety of solutions that are impossible using classical …

Multiphoton interference reveals strictly nonclassical phenomena. Its applications range
from fundamental tests of quantum mechanics to photonic quantum information processing …

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 present several entanglement criteria in terms of the quantum Fisher information that
help to relate various forms of multipartite entanglement to the sensitivity of phase …

In this paper we study the subset of generalized quantum measurements on finite
dimensional systems known as local operations and classical communication (LOCC) …

One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

We present the experimental detection of genuine multipartite entanglement using
entanglement witness operators. To this aim, we introduce a canonical way of constructing …

We introduce a family of separability criteria that are based on the existence of extensions of
a bipartite quantum state ρ to a larger number of parties satisfying certain symmetry …
