17 March 2010, nature.com: Scientists supersize quantum mechanics Citat: "...it is possible for the same particle to be doing two contradictory things simultaneously...Next, the researchers put the quantum circuit into a superposition of 'push' and 'don't push', and connected it to the paddle. Through a series of careful measurements, they were able to show that the paddle was both vibrating and not vibrating simultaneously..."

American Association for the Advancement of Science (2010, December 16). Science's breakthrough of the year: The first quantum machine. ScienceDaily Citat: "...They even managed to put the gadget in both states at once, so that it literally vibrated a little and a lot at the same time -- a bizarre phenomenon allowed by the weird rules of quantum mechanics..."
University of California, Santa Barbara (2010, March 18). Quantum mechanics demonstrated in motion of objects large enough to see with naked eye. ScienceDaily Citat: "...They were able to create a single phonon...While exchanging this energy, the qubit and resonator become "quantum entangled," such that measuring the qubit forces the mechanical resonator to "choose" the vibrational state in which it should remain...[]...In a related experiment, they placed the mechanical resonator in a quantum superposition, a state in which it simultaneously had zero and one quantum of excitation. This is the energetic equivalent of an object being in two places at the same time..."
