Entanglement made measurable

Subjects Electronic properties and materialsMagnetic properties and materials A resonant inelastic X-ray scattering interferometric approach exposes a highly entangled electronic ground state in a pyrochlore iridate, linking quantum entanglement to intertwined symmetry-breaking orders in a correlated metal near a metal–insulator transition.
