dc.description.abstract
Optomechanical systems show great potential as quantum transducers and information storage devices for use in future hybrid quantum networks and offer novel strategies for quantum state preparation to explore macroscopic quantum phenomena. Towards these goals, deterministic control of optomechanical interactions in the strong coupling regime represents an important strategy for efficient utilization of quantum degrees of freedom in mechanical systems. While strong coupling has been demonstrated in both electromechanical and optomechanical systems, it has proven difficult to identify a robust optomechanical system that features the low loss and high coupling rates required for more sophisticated control of mechanical motion. In this paper, we demonstrate robust strong coupling between multiple long-lived phonon modes of a bulk acoustic wave (BAW) resonator and a single optical cavity mode. We show that this so-called "multimode strong coupling" regime can be a powerful tool to shape and control decoherence pathways through nontrivial forms of mode hybridization. Using frequency- and time-domain measurements, we identify hybridized modes with lifetimes that are significantly longer than that of any mode of the uncoupled system. This surprising effect, which results from the interference of decay channels, showcases the use of multimode strong coupling as a general strategy to mitigate extrinsic loss mechanisms. Moreover, the phonons supported by BAW resonators have a collection of properties, including high frequencies, long coherence times, and robustness against thermal decoherence, making this optomechanical system particularly enticing for applications such as quantum transduction and memories. These results show that our system can be used to study novel phenomena in a previously unexplored regime of optomechanics and could be an important building block for future quantum devices.
