Entanglement detection, which signifies the task of distinguishing entangled states from
separable states, can be generally performed by realizing entanglement witnesses via local …

We demonstrate a hierarchy of various classes of quantum correlations on experimentally
prepared two-qubit Werner-like states with controllable white noise. Werner states, which …

We propose and experimentally implement an efficient procedure based on entanglement
swapping to determine the Bell nonlocality measure of Horodecki et al.[Phys. Lett. A 200 …

Identification, and subsequent quantification of quantum correlations, is critical for
understanding, controlling, and engineering quantum devices and processes. We derive …

We revisit the problem of detection of entanglement of an unknown two-qubit state using
minimal resources. Using weak values and just two copies of an arbitrary two-qubit state, we …

The paper suggest employing machine learning for resource-efficient classification of
quantum correlations in entanglement distribution networks. Specifically, artificial neural …

We demonstrate that nonlinear entanglement witnesses can be made particularly useful for
entanglement detection in hyperentangled or multilevel states. We test this idea …

Hyperentanglement is the quantum system entangled in several degrees of freedom (DOFs),
which has attracted extensive attention in quantum communication. In the practical …
