Entangled spin states are created by implanting muons into single-crystal

{LiY}_{0.95} {Ho}_{0.05} F_{4}

to form a cluster of correlated, dipole-coupled local magnetic moments. The resulting states have well-defined energy levels allowing experimental manipulation of the state populations by electromagnetic excitation. Experimental control of the evolution of the muon spin polarization is demonstrated through application of continuous, radio-frequency electromagnetic excitation fields. A semiclassical model of quantum, dipole-coupled spins interacting with a classical, oscillating magnetic field accounts for the muon spin evolution. On application of the excitation field, this model shows how changes in the state populations lead to the experimentally observed effects, thus enabling a spectroscopic probe of entangled spin states with muons.

纠缠氟-μ子-氟系统中状态种群的射频操纵

纠缠自旋态是通过将μ子植入单晶来产生的

锂_{0.95} 何_{0.05} F_{4}

形成一组相关的偶极耦合局部磁矩。由此产生的状态具有明确定义的能级，允许通过电磁激发对状态种群进行实验操作。通过应用连续的射频电磁激发场，证明了对 μ 子自旋极化演化的实验控制。量子偶极耦合自旋与经典振荡磁场相互作用的半经典模型解释了 μ 子自旋演化。在激发场的应用中，该模型显示了状态种群的变化如何导致实验观察到的效应，从而实现了与 μ 子纠缠自旋态的光谱探测。
