The progression of technology relies in part on the identification and control of components, such as confined electrons or photons, from which systems of greater complexity are built. Once a curiosity, it now looks like nanomechanical systems can also have good, robust properties for classical and quantum devices. I will discuss our recent work on controlling phonons at the quantum level. We have introduced a way to engineer a sound-based analogue of cavity-QED allowing for composite quantum objects called phonitons to be formed [1]. We show how this system can be used to probe phonon-qubit (sound-matter) interactions and properties, form complex many-body systems, and be practically realized. Recently, we have shown [2] how an on-chip version of this system can be constructed allowing integration with other phononic components such as photon-phonon translators.
