Controlled Growth of Rare-Earth-Doped TiO2 Thin Films on III-V Semiconductors for Hybrid Quantum Photonic Interfaces
{{output}}
Quantum photonic networks require two distinct functionalities: bright single-photon sources and long-lived quantum memories. III-V semiconductor quantum dots (QDs) excel as deterministic and coherent photon emitters, while rare-earth ions such as erbium (Er3+... ...
