  text: We propose an efficient microwave-photonic modulator as a resource for stationary
    entangled microwave-optical fields and develop the theory for deterministic entanglement
    generation and quantum state transfer in multi-resonant electro-optic systems.
    The device is based on a single crystal whispering gallery mode resonator integrated
    into a 3D-microwave cavity. The specific design relies on a new combination of
    thin-film technology and conventional machining that is optimized for the lowest
    dissipation rates in the microwave, optical, and mechanical domains. We extract
    important device properties from finite-element simulations and predict continuous
    variable entanglement generation rates on the order of a Mebit/s for optical pump
    powers of only a few tens of microwatts. We compare the quantum state transfer
    fidelities of coherent, squeezed, and non-Gaussian cat states for both teleportation
    and direct conversion protocols under realistic conditions. Combining the unique
    capabilities of circuit quantum electrodynamics with the resilience of fiber optic
    communication could facilitate long-distance solid-state qubit networks, new methods
    for quantum signal synthesis, quantum key distribution, and quantum enhanced detection,
    as well as more power-efficient classical sensing and modulation.
