Abstract
We propose theory for a reversible quantum transducer connecting superconducting qubits and optical photons using acoustic waves in piezoelectrics. The proposed device consists of an integrated acousto-optic resonator that utilizes stimulated Brillouin scattering for phonon-photon conversion and piezoelectric effect for coupling of phonons to qubits. We evaluate the phonon-photon coupling rate and show that the required power of the optical pump as well as the other device parameters providing full and faithful quantum conversion is feasible for implementation with the state-of-the-art integrated acousto-optics.
