Quantum Transducers: Materials, Devices, and Heterogeneous Integration
Hybrid quantum networks rely on faithful quantum state transfer between disparate physics elements operating at dissimilar frequencies and hosted in distinct materials. Chip-integrated quantum transducers enable high Q cavities with ultrasmall mode volumes and provide enhanced coupling between carriers while maintaining their quantum correlations. Here the transduction materials play a central role as they must meet stringent requirements for simultaneously providing strong nonlinearity and very low carrier loss. In this presentation, I will discuss the general criteria, specific implementation and future directions for materials, devices engineering, and heterogeneous integration in quantum transducer development.
