Fabricating tiny mechanical structures where the vibrational motion is purely quantum mechanical is a long-standing goal in physics, and a parallel goal is the development of a scheme for observing and controlling such tiny motions. By coupling a tiny mechanical resonator to a superconducting two-level quantum system (qubit), the state of the superconducting qubit can be measured through its influence on the vibrations of the resonator, a demonstration of nanomechanical read-out of quantum interference.
