Can a tiny piece of metal exist in a quantum state spread across multiple locations at once? Researchers at the University of Vienna say yes.
Writing in Nature, scientists from the University of Vienna and the University of Duisburg-Essen report that even relatively large nanoparticles made of thousands of sodium atoms still obey the laws of quantum mechanics. Their work represents one of the most rigorous tests yet of quantum behavior at a near macroscopic scale.
