Insider Brief
TU Wien researchers found evidence of high multipartite quantum entanglement in a centimetre-sized strange-metal crystal made of cerium, palladium and silicon.
The team used quantum Fisher information and neutron-scattering measurements to show that the material’s response could not be explained by independent particles and involved groups of at least nine entangled entities.
The findings may help explain unusual strange-metal behavior, including low-noise electrical current, and could point to future uses in quantum metrology.
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 provide a direct glimpse into the quantum world?
