We introduce the class of Genuinely Local Operation and Shared Randomness (LOSR) Multipartite Nonlocal correlations, that is, correlations between N parties that cannot be obtained from unlimited shared randomness supplemented by any composition of (N−1)-shared causal Generalized-ProbabilisticTheory (GPT) resources. We then show that noisy N -partite GHZ quantum states as well as the 3-partite W quantum state can produce such correlations. This proves, if the operational predictions of quantum…

Bell's theorem shows that correlations created by a single entangled quantum state cannot be reproduced classically. Such correlations are called nonlocal. They are the elementary manifestation of a…

While Bell nonlocality of a bipartite system is counterintuitive, multipartite nonlocality in our many-body world turns out to be even more so. Recent theoretical study reveals in a theory-agnostic…

### Network nonlocality via rigidity of token counting and color matching

- Computer SciencePhysical Review A
- 2022

This paper introduces two families of strategies to produce nonlocal correlations in networks and shows that TC and CM distributions are rigidity in wide classes of networks, meaning that there is essentially a unique classical strategy to simulate such correlations.

- Computer Science

A new hierarchy of necessary conditions is introduced, its equivalence to the Scalar Extension is proved and its convergence in the case of the simplest network, the bilocal scenario is characterised.

- Computer Science

It is shown that the postselected inflation framework is mathematically equivalent to the standard inflation framework: in that respect, it allow to gain further insights into the convergence proof of the inflation hierarchy of Navascuès and Wolfe, and extend it to the case of multi-network scenarios.

### Genuine Network Multipartite Entanglement.

- PhysicsPhysical review letters
- 2020

This work proposes an alternative definition for genuine multipartite entanglement, whereby a quantum state is genuinely network k-entangled if it cannot be produced by applying local trace-preserving maps over several (k-1)-partite states distributed among the parties, even with the aid of global shared randomness.

### Genuine Multipartite Nonlocality Is Intrinsic to Quantum Networks.

- PhysicsPhysical review letters
- 2021

It is found that any network where the parties are connected by bipartite pure entangled states is genuine multipartite nonlocal, independently of the amount of entanglement in the shared states and of the topology of the network.

A complete set of game-theoretic conditions equivalent to the existence of a transformation from one quantum channel into another one, by means of classically correlated pre/post processing maps only, are provided, mirroring the resource theory of entanglement in quantum states.

The generation of (Bell-)nonlocal correlations, i.e., correlations leading to the violation of a Bell-like inequality,

### Why standard entanglement theory is inappropriate for the study of Bell scenarios

- Physics
- 2020

It is argued that, in spite of the near-universal endorsement of the LOCC paradigm by the quantum information community, this is the wrong choice for one of the most prominent applications of entanglement theory, namely, the study of Bell scenarios and the nonclassicality of correlations should be quantified instead by local operations and shared randomness (LOSR).

This work investigates constraints on correlations in networks under the natural assumptions of no-signaling and independence of the sources, and applies inflation technique to the no-input/binary-output triangle network, and shows that it admits non-trilocal distributions.
