A maximally entangled state becomes "less entangled" when measured by two observes, one of whom is in an accelerating inertial reference frame with respect to the other. I've been thinking a bit lately about the relationship between electron correlation and entanglement, so perhaps this has some application to the problem of relativistic electrons in heavy (high-Z) atoms. Maybe not.
