I'm currently looking at a quantum electro-mechanical system consisting of a cantilever coupled to a trapped ion as described in our previous work [Phys. Rev. A 72, 041405(R) (2005)]. Various state of the cantilever can be prepared by preparing the state of the ion and transfering its state to the cantilever.
