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 …

Entanglement swap** and quantum correlations via symmetric joint measurements

CX Huang, XM Hu, Y Guo, C Zhang, BH Liu… - Physical Review Letters, 2022 - APS
We use hyperentanglement to experimentally realize deterministic entanglement swap**
based on quantum elegant joint measurements. These are joint projections of two qubits …

Bilocal Bell inequalities violated by the quantum elegant joint measurement

A Tavakoli, N Gisin, C Branciard - Physical review letters, 2021 - APS
Network Bell experiments give rise to a form of quantum nonlocality that conceptually goes
beyond Bell's theorem. We investigate here the simplest network, known as the bilocality …

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 develo** quantum technology and an increasingly promising test-bed …

Entanglement 25 years after quantum teleportation: Testing joint measurements in quantum networks

N Gisin - Entropy, 2019 - mdpi.com
Twenty-five years after the invention of quantum teleportation, the concept of entanglement
gained enormous popularity. This is especially nice to those who remember that …

Experimental violation of n-locality in a star quantum network

D Poderini, I Agresti, G Marchese, E Polino… - Nature …, 2020 - nature.com
The launch of a satellite capable of distributing entanglement through long distances and
the first loophole-free violation of Bell inequalities are milestones indicating a clear path for …

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 …

Genuine multipartite nonlocality is intrinsic to quantum networks

P Contreras-Tejada, C Palazuelos, JI de Vicente - Physical Review Letters, 2021 - APS
Quantum entanglement and nonlocality are inextricably linked. However, while
entanglement is necessary for nonlocality, it is not always sufficient in the standard Bell …

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 …
