Hybrid systems with bulk acoustic wave resonators*

The ability to engineer and manipulate different varieties of quantum mechanical objects allows us to take advantage of their unique properties and create powerful hybrid technologies. Our recent work indicates that bulk acoustic wave (BAW) resonators can be used as a highly coherent mechanical object for implementing and understanding quantum systems. In this talk, I will focus on our demonstration of strong coupling between a BAW resonator and a superconducting qubit. The long coherence times and high cooperativity of the system enable quantum operations on the phonons. In addition, I will briefly describe our experiments using a combination of microwave circuits, BAW resonators, and infrared optics for transduction and high sensitivity measurements of materials properties.
