我们发现，氮空位（NV）中心的金刚石与悬浮的碳纳米管进行直流电流接口可以促进自旋纳米机械混合装置。我们证明了一个单一的NV自旋和悬浮纳米管的振动模式之间的强磁力相互作用可以通过外部控制系统参数进行设计和动态调谐。这种具有强的、内在的和可调谐的磁力耦合的自旋纳米机械设置允许构建具有NV中心和碳基纳米结构的混合量子器件，以及具有自旋量子比特的声子介导的量子信息处理。
We show that nitrogen-vacancy (NV) centers in diamond interfaced with a suspended carbon nanotube carrying a dc current can facilitate a spin-nanomechanical hybrid device. We demonstrate that strong magnetomechanical interactions between a single NV spin and the vibrational mode of the suspended nanotube can be engineered and dynamically tuned by external control over the system parameters. This spin-nanomechanical setup with strong, intrinsic, and tunable magnetomechanical couplings allows for the construction of hybrid quantum devices with NV centers and carbon-based nanostructures, as well as phonon-mediated quantum information processing with spin qubits.
