自旋力学研究纳米机械谐振器中自旋系统与机械振动之间的相互作用，并探索其在量子信息处理中的潜在应用。在本教程中，我们总结了各种类型的自旋机械谐振器，并讨论了类腔qed和类阱离子的自旋机械耦合过程。本文综述了利用负电荷氮空位中心和硅空位中心在金刚石中实现这些工艺的方法。讨论了在单自旋和单声子水平上可以实现量子控制的自旋力学的全量子状态的前景，并强调了应变耦合对缺陷中心轨道自由度的关键作用。
Spin-mechanics studies interactions between spin systems and mechanical vibrations in a nanomechanical resonator and explores their potential applications in quantum information processing. In this tutorial, we summarize various types of spin-mechanical resonators and discuss both the cavity-QED-like and the trapped-ion-like spin-mechanical coupling processes. The implementation of these processes using negatively charged nitrogen vacancy and silicon vacancy centers in diamond is reviewed. Prospects for reaching the full quantum regime of spin-mechanics, in which quantum control can occur at the level of both single spin and single phonon, are discussed with an emphasis on the crucial role of strain coupling to the orbital degrees of freedom of the defect centers.
