TU Wien finds 9-particle entanglement in centimeter-sized crystal in Austria
A team at TU Wien, Austria, just found quantum entanglement happening inside a centimeter-sized crystal, so not just in tiny particles anymore.
This is a big deal because it shows quantum effects in materials you can hold.
The researchers used neutron scattering and quantum Fisher information to confirm that at least nine particles were working together as an entangled group.
Their results were published in Nature Physics on June 15.
Entanglement sharpens cerium palladium silicon response
The crystal was made from cerium, palladium, and silicon — a combo belonging to a class of materials known as "strange metals" with unusual electrical properties.
These materials are linked to high-temperature superconductors and show wild quantum behaviors.
Thanks to strong entanglement, the crystal responded more sharply to changes around it.
This could lead to breakthroughs in future quantum technologies and super-precise measurement tools down the line.
