Atoms’ spins (shown here as black arrows) were connected through quantum entanglement (ribbons), so that if one atom’s spin was altered, the spin of its entangled partner would also change.

Le onde gravitazionali, previste 100 anni fa dalla Teoria della Relatività Generale di Albert Einstein, sono state rilevate da osservatori degli Stati Uniti. Importante la partecipazione di ricercatori italiani.
