Abstract: Quantum network correlations have attracted strong interest as the emergency of the new types of violations of locality. Here we investigated network nonlocal sharing in the extended bilocal scenario via weak measurements. Interestingly, network nonlocal sharing can be revealed from the multiple violation of BRGP inequalities of any Alice_{n}-Bob-Charlie_{m}, which has no counterpart in the case of Bell nonlocal sharing scenario. Such discrepancy may imply an intrinsic difference between network nonlocality and Bell nonlocality. Passive and active network nonlocal sharing as two distinct types of nonlocality sharing have been completely analyzed. In addition, noise resistance of network nonlocal sharing were also discussed.

Hierarchical certification of nonclassical network correlations [50.32788626697182]
We derive linear and nonlinear Bell-like inequalities for networks, whose violation certifies the absence of a minimum number of classical sources in them. We insert this assumption, which leads to results more amenable to certification in experiments.

Hidden Non n-locality In Linear Networks [0.0]
We study hidden nonlocality in a linear network with independent sources. Nonbilocality is observed even when one of the sources distributes a mixed two-qubit separable state. We find that local filtering enhances the robustness to noise.

Experimental full network nonlocality with independent sources and strict locality constraints [59.541438315564854]
Nonlocality in networks gives rise to phenomena radically different from that in standard Bell scenarios. We experimentally observe full network nonlocality in a network where the source-independence, locality, and measurement-independence loopholes are closed. Our experiment violates known inequalities characterizing non-full network nonlocal correlations by over five standard deviations.

Certification of non-classicality in all links of a photonic star network without assuming quantum mechanics [52.95080735625503]
Full network nonlocality goes beyond standard nonlocality in networks by falsifying any model in which at least one source is classical. We report on the observation of full network nonlocality in a star-shaped network featuring three independent sources of photonic qubits and joint three-qubit entanglement-swapping measurements.

From nonlocality quantifiers for behaviors to nonlocality quantifiers for states [58.720142291102135]
We define an alternative way of quantifying nonlocality of states based on Bell nonlocality of behaviors, called the trace-weighted nonlocal volume. The construction is based on the nonlocal volume, a quantifier of nonlocality for states that counts the volume of the set of measurements that give rise to nonlocal behaviors when applied to this state, plus the trace distance. We show that the weak anomaly of nonlocality for the (2, 2, 3) scenario persists, but the local minimum for nonlocality with the trace-weighted nonlocal volume occurs in a different state as compared to the minimum for the

Proofs of network quantum nonlocality aided by machine learning [68.8204255655161]
We show that the family of quantum triangle distributions of [DOI40103/PhysRevLett.123.140] did not admit triangle-local models in a larger range than the original proof. We produce a large collection of network Bell inequalities for the triangle scenario with binary outcomes, which are of independent interest.

Full network nonlocality [68.8204255655161]
We introduce the concept of full network nonlocality, which describes correlations that necessitate all links in a network to distribute nonlocal resources. We show that the most well-known network Bell test does not witness full network nonlocality. More generally, we point out that established methods for analysing local and theory-independent correlations in networks can be combined in order to deduce sufficient conditions for full network nonlocality.
