论文摘要
用于混合量子技术的稀土离子掺杂晶体是固态物理界越来越感兴趣的领域。我们较早地从理论上提出了一种机械谐振器的混合方案，该方案是由稀土掺杂的单晶结构制成的。稀土离子掺杂剂具有对晶体应变敏感的吸收能，因此可以将离子与晶体悬臂的弯曲运动息息。在这里，我们介绍了基于我们成功使用的重点离子梁蚀刻技术的设计和制造方法，以创建这种微观谐振器，以及环境的设计，该技术将允许研究谐振器的量子行为。
Rare-earth ion doped crystals for hybrid quantum technologies is an area of growing interest in the solid-state physics community. We have earlier theoretically proposed a hybrid scheme of a mechanical resonator which is fabricated out of a rare-earth doped mono-crystalline structure. The rare-earth ion dopants have absorption energies which are sensitive to crystal strain, and it is thus possible to couple the ions to the bending motion of the crystal cantilever. Here, we present the design and fabrication method based on focused-ion-beam etching techniques which we have successfully employed in order to create such microscale resonators, as well as the design of the environment which will allow to study the quantum behavior of the resonators.
