Theory of Fluxonium-Acoustic Hybrid Systems

We present theoretical work on hybrid quantum systems that combine superconducting fluxonium qubits with acoustic resonators. These systems offer a promising route to explore novel coupling principles between electrical and mechanical degrees of freedom in the quantum regime. Our theoretical work develops a framework to describe these coupling mechanis, and identifies key design considerations for possible devices. Our findings highlight the potential for integrating novel superconducting qubits with circuit quantum acoustodynamics systems.
