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.

Optically Addressing Single Rare-Earth Ions in a Nanophotonic Cavity

Tian Zhong, Jonathan M. Kindem, John G. Bartholomew +8 more

We demonstrate optical probing of spectrally resolved single Nd^{3+} rare-earth ions in yttrium orthovanadate. The ions are coupled to a photonic crystal resonator and show strong enhancement of the optical emission rate via the Purcell effect, resulting in near radiatively limited single photon emission. The measured high coupling cooperativity between a single photon and the ion allows for the observation of coherent optical Rabi oscillations. This could enable optically controlled spin qubits, quantum logic gates, and spin-photon interfaces for future quantum networks.
