Abstract

${}^{171}$Yb${}^{3+}$ ions in yttrium orthovanadate are promising candidates for building quantum networks, based on their excellent optical and spin properties and access to a secondary nuclear-spin quantum register. In this study the authors transfer GaAs photonic crystal nanobeam resonators to the surface of the host YVO${}_{4}$ to enhance the optical transitions of the Yb${}^{3+}$ ions and efficiently collect the emitted photons. This hybrid quantum photonic interface facilitates addressing of single Yb${}^{3+}$ ions and paves the way for the implementation of a scalable photonic architecture in the near infrared.
