A two-way quantum interface for linking Sr+ transition at 422nm to the telecommunications C-band

A two-way quantum interface for linking Sr+ transition at 422nm to the telecommunications C-band
We report a single-stage bi-directional interface capable of linking Sr+
trapped ion qubits in a long-distance quantum network. Our interface converts
photons between the Sr+ emission wavelength at 422 nm and the telecoms
C-band to enable low-loss transmission over optical fiber. We have achieved
both up- and down-conversion at the single photon level with efficiencies of
9.4 % and 1.1 % respectively. Furthermore, we demonstrate that the noise
introduced during the conversion process is sufficiently low to implement
high-fidelity interconnects suitable for quantum networking.

Abstract

We report a single-stage bi-directional interface capable of linking Sr+
trapped ion qubits in a long-distance quantum network. Our interface converts
photons between the Sr+ emission wavelength at 422 nm and the telecoms
C-band to enable low-loss transmission over optical fiber. We have achieved
both up- and down-conversion at the single photon level with efficiencies of
9.4 % and 1.1 % respectively. Furthermore, we demonstrate that the noise
introduced during the conversion process is sufficiently low to implement
high-fidelity interconnects suitable for quantum networking.
