    Enlarge Image Springboard. This little vibrating widget has been eased into the simplest quantum state of motion. Credit: O'Connell et al., Nature, Advance Online Publication (2010) The weird rules of quantum mechanics state that a tiny object can absorb energy only in discrete amounts, or quanta, and can literally be in two places simultaneously. Those mind-bending tenets have been amply demonstrated in experiments with electrons, photons, atoms, and molecules. Ironically, though, physicists have never observed such bizarre quantum-mechanical effects in the motion of a human-made mechanical device. Now, Andrew Cleland, John Martinis, and colleagues at the University of California,...
