The ability to fabricate devices that demonstrate quantum behavior, as opposed to being restricted to what nature has given us, has opened up the possibility of technologies based on the laws of quantum physics instead of classical physics. The prime example of this is the superconducting qubit at the core of a quantum processor. Another class of fabricated devices that are beginning to demonstrate quantum behavior is that of nanoscale mechanical resonators. Such devices promise force and torque sensors operating at or beyond the standard quantum limit, and novel technologies such as quantum-level wavelength transducers. I will tell you about our efforts to develop such technologies and some of the fun physics we have uncovered along the way.
