论文摘要
我们研究了由超导通量量和钻石中的氮无效颜色中心组成的混合系统中特殊点的外观。我们通过分析模型空间参数来讨论控制特殊点的生成的可能性。出现特殊点的特征之一，它是与观测值随着时间的变化的指数衰减行为的背离。我们通过计算每个子系统的降低密度矩阵，研究不同初始状态的时间演变。我们介绍了不同可观察物的稳定行为所获得的结果。我们分析了挤压自旋态和抗孔自旋状态的外观。
We study the appearance of Exceptional Points in a hybrid system composed of a superconducting flux-qubit and an ensemble of nitrogen-vacancy colour centres in diamond. We discuss the possibility of controlling the generation of Exceptional Points, by the analysis of the model space parameters. One of the characteristic features of the presence of Exceptional Points, it is the departure from the exponential decay behaviour of the observables as a function of time. We study the time evolution of different initial states, in the presence of the hybrid system, by computing the reduced density matrix of each subsystem. We present the results we have obtained for the steady behaviour of different observables. We analyse the appearance of Squeezed Spin States and of anti-Squeezed Spin States.
