“the team generated what is known as the "elegant distribution," a specific pattern of correlations predicted to exhibit this network-dependent behavior.”
SINGLE SOURCE
While the general experiment is corroborated, the specific term 'elegant distribution' is only mentioned in the context of the primary article's narrative; the provided search results for this specific phrase are irrelevant (linguistic databases).

“Ning-Ning Wang et al, Experimental Genuine Quantum Nonlocality in the Triangle Network, Physical Review Letters (2026). DOI: 10.1103/5hhc-rw3t. On arXiv: DOI: 10.48550/arxiv.2401.15428”
DISPUTED
The claim cites a publication date of 2026, which is in the future relative to the current date. However, the arXiv identifier (2401.15428) suggests a 2024 submission. The DOI provided (10.1103/5hhc-rw3t) does not follow standard Physical Review Letters DOI formats, and the date 2026 is anachronistic.
