New protocol to detect entanglement of many-particle quantum states Quantum systems consisting of many particles can enter highly intricate states with strong so-called multiparticle entanglement. A new-found theoretical relation now allows extracting it with standard tools available in scattering experiments. Credit: IQOQI/Ritsch In quantum theory, interactions among particles create fascinating correlations […]


NASA’s New Horizons spacecraft has observed what looks like a giant “bite mark” on the planet’s surface.
