Bell nonlocality in networks

A Tavakoli, A Pozas-Kerstjens, MX Luo… - Reports on Progress in …, 2022 - iopscience.iop.org
Bell's theorem proves that quantum theory is inconsistent with local physical models. It has
propelled research in the foundations of quantum theory and quantum information science …

Full network nonlocality

A Pozas-Kerstjens, N Gisin, A Tavakoli - Physical review letters, 2022 - APS
Networks have advanced the study of nonlocality beyond Bell's theorem. Here, we introduce
the concept of full network nonlocality, which describes correlations that necessitate all links …

[HTML][HTML] Experimental nonclassicality in a causal network without assuming freedom of choice

E Polino, D Poderini, G Rodari, I Agresti… - Nature …, 2023 - nature.com
In a Bell experiment, it is natural to seek a causal account of correlations wherein only a
common cause acts on the outcomes. For this causal structure, Bell inequality violations can …

[HTML][HTML] Certification of non-classicality in all links of a photonic star network without assuming quantum mechanics

NN Wang, A Pozas-Kerstjens, C Zhang, BH Liu… - Nature …, 2023 - nature.com
Networks composed of independent sources of entangled particles that connect distant
users are a rapidly developing quantum technology and an increasingly promising test-bed …

Causal networks and freedom of choice in bell's theorem

R Chaves, G Moreno, E Polino, D Poderini, I Agresti… - PRX Quantum, 2021 - APS
Bell's theorem is typically understood as the proof that quantum theory is incompatible with
local-hidden-variable models. More generally, we can see the violation of a Bell inequality …

Experimental genuine tripartite nonlocality in a quantum triangle network

A Suprano, D Poderini, E Polino, I Agresti, G Carvacho… - PRX Quantum, 2022 - APS
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 …

Experimental full network nonlocality with independent sources and strict locality constraints

XM Gu, L Huang, A Pozas-Kerstjens, YF Jiang, D Wu… - Physical Review Letters, 2023 - APS
Nonlocality arising in networks composed of several independent sources gives rise to
phenomena radically different from that in standard Bell scenarios. Over the years, the …

Certifying Network Topologies and Nonlocalities of Triangle Quantum Networks

YL Mao, H Chen, B Guo, S Liu, ZD Li, MX Luo, J Fan - Physical Review Letters, 2024 - APS
Quantum networks promise unprecedented advantages in information processing and open
up intriguing new opportunities in fundamental research, where network topology and …

Sharing nonlocality in a quantum network by unbounded sequential observers

SS Mahato, AK Pan - Physical Review A, 2022 - APS
Of late, there has been an upsurge of interest in studying the sequential sharing of various
forms of quantum correlations, viz., nonlocality, preparation contextuality, coherence, and …

Ab initio experimental violation of Bell inequalities

D Poderini, E Polino, G Rodari, A Suprano… - Physical Review …, 2022 - APS
The violation of a Bell inequality is the paradigmatic example of device-independent
quantum information: The nonclassicality of the data is certified without the knowledge of the …
