微波和光学频率之间的量子转换对于连接量子网络中的超导量子平台非常重要。稀土离子系综由于其在微波和光学频率的集体相干性质，是实现这种转换的有希望的候选者。铒离子由于其电信波长的光学跃迁与光纤通信网络和组件兼容而特别令人感兴趣。本文报道了掺Er~(3+)：YVO_4(Er3+：YVO_4)晶体的光学和电子自旋性质，包括高分辨光谱分析、电子顺磁共振研究和经典场微波-光学转换的初步演示。高吸收的光学跃迁和窄的系综线宽使Er3+：YVO4有望用于磁光量子转换。
Quantum transduction between microwave and optical frequencies is important for connecting superconducting quantum platforms within a quantum network. Ensembles of rare-earth ions are promising candidates to achieve this conversion due to their collective coherence properties at microwave and optical frequencies. Erbium ions are of particular interest because of their telecom wavelength optical transitions that are compatible with fiber communication networks and components. Here, we report the optical and electron spin properties of erbium-doped yttrium orthovanadate (Er3+:YVO4), including high-resolution optical spectroscopy, electron paramagnetic resonance studies, and an initial demonstration of microwave to optical conversion of classical fields. The highly absorptive optical transitions and narrow ensemble linewidths make Er3+:YVO4 promising for magneto-optic quantum transduction.
