In both classical and quantum many-body physics, it is a core issue to characterize statistical
correlations among different degrees of freedom. From this point of view, a natural question …

Integrated optical components on lithium niobate play a major role in standard high-speed
communication systems. Over the last two decades, after the birth and positioning of …

Over the past few decades, experimental tests of Bell-type inequalities have been at the
forefront of understanding quantum mechanics and its implications. These strong bounds on …

From the physical point of view entanglement witnesses (EWs) define a universal tool for
analysis and classification of quantum entangled states. From the mathematical perspective …

The future of quantum communication relies on quantum networks composed by observers
sharing multipartite quantum states. The certification of multipartite entanglement will be …

Quantum networks are the center of many of the recent advances in quantum science, not
only leading to the discovery of new properties in the foundations of quantum theory but also …

Standard procedures for entanglement detection assume that experimenters can exactly
implement specific quantum measurements. Here, we depart from such idealizations and …

Quantum correlations, often observed as violations of Bell inequalities,,,,, are critical to our
understanding of the quantum world, with far-reaching technological,,, and fundamental …

We present an approach to estimate the operational distinguishability between an entangled
state and any separable state directly from measuring an entanglement witness. We show …

Many future quantum technologies rely on the generation of entangled states. Quantum
devices will require verification of their operation below some error threshold, but the …
