A hybrid quantum photonic interface for $^{171}$Yb solid-state qubits

Chun-Ju Wu, Daniel Riedel, Andrei Ruskuc +3 more

$^{171}$Yb$^{3+}$ in YVO$_4$ is a promising candidate for building quantum networks with good optical addressability, excellent spin properties and a secondary nuclear-spin quantum register. However, the associated long optical lifetime necessitates coupling to optical resonators for faster emission of single photons and to facilitate control of single $^{171}$Yb ions. Previously, single $^{171}$Yb ions were addressed by coupling them to monolithic photonic crystal cavities fabricated via lengthy focused ion beam milling. Here, we design and fabricate a hybrid platform based on ions coupled to the evanescently decaying field of a GaAs photonic crystal cavity. We experimentally detect and demonstrate coherent optical control of single $^{171}$Yb ions. For the most strongly coupled ions, we find a 64 fold reduction in lifetime. The results show a promising route towards a quantum network with $^{171}$Yb:YVO$_4$ using a highly scalable platform.

Near-infrared hybrid quantum photonic interface for 171Yb3+ solid-state qubits

Chun-Ju Wu, Daniel Riedel, Andrei Ruskuc +3 more

${}^{171}$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.
