纠缠自旋态是通过将μ子注入单晶中形成一个相关的偶极耦合局部磁矩簇而产生的。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。实验控制的μ子自旋极化的演变证明通过应用程序的连续，射频电磁激发场。一个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子自旋的演化。在激发场的应用中，该模型显示了态布居的变化如何导致实验观察到的效应，从而使μ子纠缠自旋态的光谱探测成为可能。
Entangled spin states are created by implanting muons into single-crystalto 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.
