Query: Cryogenic microwave-to-optical conversion using a triply-resonant
  lithium niobate on sapphire transducer   Quantum networks are likely to have a profound impact on the way we compute
and communicate in the future. In order to wire together superconducting
quantum processors over kilometer-scale distances, we need transducers that can
generate entanglement between the microwave and optical domains with high
fidelity. We present an integrated electro-optic transducer that combines
low-loss lithium niobate photonics with superconducting microwave resonators on
a sapphire substrate. Our triply-resonant device operates in a dilution
refrigerator and converts microwave photons to optical photons with an on-chip
efficiency of $6.6\times 10^{-6}$ and a conversion bandwidth of 20 MHz. We
discuss design trade-offs in this device, including strategies to manage
acoustic loss, and outline ways to increase the conversion efficiency in the
future.
