摘要

Rare-earth ions are attractive platforms for quantum optics and quantum information technologies because they exhibit long-lived optical and spin coherence. In parallel, rapid progress in nanophotonics and nanophononics has accelerated the development of hybrid quantum systems including rare-earth dopants in solid-state devices. This review highlights recent advances in rare-earth-based opto-electro-mechanical architecture, where phononic structures enable acoustic tailoring of optical properties of rare-earth ions. We reveal fundamental physics on the interaction among telecom-wavelength photons, long-lived electrons, and acoustic phonons in rare-earth-doped materials and provide potential technological implications of this emerging field.
