In a demonstration of just how weird the quantum world is, scientists at the National Institute of Standards and Technology (NIST) have manipulated six atoms into spinning together in two opposite directions at the same time. This so-called Schrödinger “cat” state was achieved by entangling six beryllium ions (charged atoms) so that their nuclei were […]
