Can large objects behave according to quantum rules? A strange metal crystal is forcing scientists to rethink the answer

Quantum entanglement: Scientists have detected quantum entanglement in a centimeter-sized crystal. This material, known as a strange metal, exhibits collective quantum behavior. Researchers used neutron scattering and quantum Fisher information to observe this phenomenon. The findings suggest groups of at least nine quantum-entangled entities act together. This discovery could advance understanding of materials for future technologies.
