Wanted: little levers to probe the quantum divide - New Scientist - New Scientist: "When two or more objects exist in a "superposition" of linked quantum states, they are said to be entangled. The researchers suggest putting two cantilevers, each with a tiny magnet at its tip, near an ultra-cold ensemble of atoms called a Bose-Einstein condensate. In a BEC all the atoms share the same quantum state. Vibrating one cantilever creates a magnetic field, which causes the atoms in the BEC to move. This motion in turn causes the magnets at the tip of the other cantilever to move, causing the cantilever to vibrate. Under such a system, the two levers should become entangled."
