Abstract summary: We experimentally obtain quantum correlations in a triangle network structure, and provide solid evidence of its nonlocality. We use machine learning tools to estimate the distance of the experimentally obtained correlation to the local set, and through the violation of a family of conjectured inequalities tailored for the triangle network.

Abstract: In the last decade, it was understood that quantum networks involving several independent sources of entanglement which are distributed and measured by several parties allowed for completely novel forms of nonclassical quantum correlations, when entangled measurements are performed. Here, we experimentally obtain quantum correlations in a triangle network structure, and provide solid evidence of its nonlocality. Specifically, we first obtain the elegant distribution proposed in (Entropy 21, 325) by performing a six-photon experiment. Then, we justify its nonlocality based on machine learning tools to estimate the distance of the experimentally obtained correlation to the local set, and through the violation of a family of conjectured inequalities tailored for the triangle network.

Experimental quantum triangle network nonlocality with an AlGaAs multiplexed entangled photon source [0.9092013845117769]
We show that quantum nonlocality without inputs can be demonstrated for sources with an arbitrarily small level of independence. We use a simulated triangle network to violate experimentally for the first time a Bell-like inequality. Our results allow us to deepen our understanding of network nonlocality while also pushing its practical relevance for quantum communication networks.

Quantum coherence in networks [0.0]
We show that verifying quantum coherence in a network scenario without the need for inputs is not necessary. We show that there exist probability distributions for joint outcomes of three parties in a triangular network. We derive nonlinear inequalities that are satisfied by classical correlations and find quantum states that violate them.

Guarantees on the structure of experimental quantum networks [105.13377158844727]
Quantum networks connect and supply a large number of nodes with multi-party quantum resources for secure communication, networked quantum computing and distributed sensing. As these networks grow in size, certification tools will be required to answer questions regarding their properties. We demonstrate a general method to guarantee that certain correlations cannot be generated in a given quantum network.

Enhanced Entanglement in the Measurement-Altered Quantum Ising Chain [46.99825956909532]
Local quantum measurements do not simply disentangle degrees of freedom, but may actually strengthen the entanglement in the system. This paper explores how a finite density of local measurement modifies a given state's entanglement structure.

Detecting Nontrilocal Correlations In Triangle Networks [0.0]
Correlations in quantum networks with independent sources exhibit a completely novel form of nonclassicality. A set of criteria is framed in the form of Bell-type inequalities, each of which is necessarily satisfied by trilocal correlations. measurement on a local product state basis turns out to be sufficient to generate nontrilocal correlations in some quantum networks.

Evolution of many-body systems under ancilla quantum measurements [58.720142291102135]
We study the concept of implementing quantum measurements by coupling a many-body lattice system to an ancillary degree of freedom. We find evidence of a disentangling-entangling measurement-induced transition as was previously observed in more abstract models.

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.

Experimental genuine tripartite nonlocality in a quantum triangle network [0.6745502291821955]
Quantum networks can lead to a genuine form of tripartite nonlocality, where classical models are unable to mimic the quantum predictions even if some of the parties are allowed to communicate. We show that such networks can lead to a genuine form of tripartite nonlocality, where classical models are unable to mimic the quantum predictions even if some of the parties are allowed to communicate.

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.

We show that the nonlocality of single-photon entangled states can nevertheless be revealed in a quantum network made only of beamsplitters and photodetectors. Our results show that single-photon entanglement may constitute a promising solution to generate genuine network-nonlocal correlations useful for Bell-based quantum information protocols.
