We describe a technique that allows one to perform a continuous measurement that continually projects a nano-mechanical resonator into its energy eigenstates (Fock, or number states) by employing a linear coupling with a two-state system. (That is, without the need for a quantum non-demolition coupling to the resonator.) This makes it possible to perform a measurement that exposes the quantum nature of the resonator by coupling it to a Cooper-pair Box and a superconducting transmission-line resonator.
