Abstract

Quantum nanophotonics interfacing optical photons with coherent atomic spins have the potential to revolutionize secure communications, ultra-scale sensing, distributed quantum computing, and enhanced metrology, but currently lack scalable material and device platform necessary for building robust quantum light-matter interfaces. The trivalent rare-earth ion such as erbium (Er3+) is a promising candidate for quantum interfaces because of its narrow optical transition as well as a long spin coherence time. Here, we present an epitaxial Er3+:Y2O3 on silicon platform for scalable quantum light-matter interconnect, enabling efficient spin-photon interfaces based on individual rare-earth qubits and quantum transduction via ensembles of ions.
