Curator's Take
This article is noteworthy because it provides the first experimental evidence that quantum entanglement can survive in a macroscopic “strange” metal—a state long thought to be dominated by classical thermal fluctuations—thereby extending the reach of quantum many‑body physics beyond isolated atoms or photons. The finding dovetails with recent advances in probing quantum criticality and non‑Fermi‑liquid behavior in cuprates and heavy‑fermion systems, suggesting that entanglement may be a unifying thread underlying unconventional superconductivity. If such robust entanglement can be harnessed, it could open new pathways for designing quantum materials with tailored electronic properties, although further work is needed to determine how controllable or scalable the effect truly is.

Summary
Insider Brief PRESS RELEASE — Many quantum effects can only be observed when a small number of particles is studied — individual atoms, molecules or photons, for example, carefully shielded from the rest of the world. But what about macroscopic objects, consisting of an unimaginably large number of particles? Can they, too, display effects that […]
