Nonlocal correlations in the tree-tensor-network configuration

L Yang, X Qi, J Hou - Physical Review A, 2021 - APS
The process of entanglement swapping showed that suitable measurements can generate
nonlocal correlations even from particles that never interacted directly. This fact was …

Post-quantum nonlocality in the minimal triangle scenario

A Pozas-Kerstjens, A Girardin, T Kriváchy… - New Journal of …, 2023 - iopscience.iop.org
We investigate network nonlocality in the triangle scenario when all three parties have no
input and binary outputs. Through an explicit example, we prove that this minimal scenario …

Detecting nontrilocal correlations in a triangle network

K Mukherjee - Physical Review A, 2022 - APS
Correlations in quantum networks with independent sources exhibit a completely novel form
of nonclassicality in the sense that the nonlocality of such correlations can be demonstrated …

Persistency of non--local correlations in noisy linear networks

K Mukherjee, I Chakrabarty, G Mylavarapu - Physical Review A, 2023 - APS
Linear n-local networks are compatible with quantum-repeater-based entanglement
distribution protocols. Different sources of imperfections such as error in entanglement …

Characterizing nonlocal correlations through various -locality inequalities in a quantum network

S Munshi, AK Pan - Physical Review A, 2022 - APS
The multipartite quantum networks feature multiple independent sources, in contrast to the
conventional multipartite Bell experiment involving a single source. Despite the initial …

Network nonlocality sharing via weak measurements in the generalized star network configuration

JH Wang, YJ Wang, LJ Wang, Q Chen - Physical Review A, 2022 - APS

Continuous and discrete local hidden variable theories are equivalent

Y Chen, S Xiao, K Han, Z Guo, H Cao - Information Sciences, 2023 - Elsevier
In quantum theory, Bell locality of quantum states (generally, of correlations, or boxes) is
characterized by local hidden variable models (LHVMs) given by integrals and sums. We …
