'Spooky Action' Heats Up: Atoms Entangled at Room Temperature

The world of the very small can get pretty wacky — particles can be in two or more places at once, and even become entangled, wherein actions on one entity can affect its partners across the cosmos. Physicists have broken all kinds of records in proving the existence of so-called quantum entanglement, and now, they have done it again, coupling together thousands of atoms at room temperature. This new achievement could one day be applied to enable more sensitive magnetic resonance imaging (
