We explore the three-particle spin model of an $S_1=\frac{1}{2}$ particle (e.g., an electron) interacting with two spin-coupled $S_{\text{2,3}}$ particles with exchange coupling and magnetic anisotropy. We show that in the case of $S_{2,3}=1$ particles, the coupled particle entanglement states can be prepared, controlled, and read by the $S_1$ particle. We also find that for particular resonance conditions of the magnetic anisotropy strength $D$ and exchange coupling strength $J$, the entanglement state-switching behavior is maximized and is robust against a range of anisotropic application of the exchange coupling.

各向异性交换共振作为纠缠态转换的机制

我们探索了一个的三粒子自旋模型 ${秒}_1=\frac{1}{2}$ 粒子（例如，一个电子）与两个自旋耦合的相互作用 ${秒}_{\text{2,3}}$具有交换耦合和磁各向异性的粒子。我们证明，在${秒}_{2,3}=1$ 粒子，耦合粒子纠缠状态可以由 ${秒}_1$粒子。我们还发现，对于磁各向异性强度的特定共振条件$D$ 和交换耦合强度 $J$，纠缠状态切换行为最大化，并且对交换耦合的一系列各向异性应用具有鲁棒性。
