Quantum Coherence of Rare-Earth Ions in Heterogeneous Photonic Interfaces
Henry C. Hammer, Hassan A. Bukhari, Yogendra Limbu +6
Harnessing rare-earth ions in oxides for quantum networks requires integration with bright emitters in III-V semiconductors, but local disorder and interfacial noise limit their op…
Controlled growth of rare-earth-doped TiO thin films on III-V semiconductors for hybrid quantum photonic interfaces
Henry C. Hammer, Caleb Whittier, Nathan A. Helvy +3
Quantum photonic networks require two distinct functionalities: bright single-photon sources and long-lived quantum memories. III-V semiconductor quantum dots excel as deterministi…
