摘要：
耗散量子系统在适当条件下可在稳态下展现二分或多体纠缠。这些量子关联的存在及其性质取决于相关模型参数。在此，我们表征了与三个离子组成的小型离子链（该离子链与泵浦光学腔色散耦合）空间结构相关的稳态纠缠。在半经典近似下，我们描述了离子链的纠缠、空间组织与振动模式之间的关系。随着泵浦强度增加，我们的系统经历了从滑动构型到钉扎构型的转变，在钉扎构型中离子被从光势的最大值处排出。稳态纠缠的特征强烈依赖于所达到的钉扎构型类型。我们识别了导致纠缠稳态的场景，分析了缺陷形成对不同系统划分间纠缠的影响，并观察到了多体量子关联的存在。
英文摘要：
Dissipative quantum systems can under appropriate conditions exhibit bi- or multi-partite entanglement at the steady state. The presence and properties of these quantum correlations depend on the relevant model parameters. Here, we characterize the steady-state entanglement in connection with the spatial structure of a small chain of three ions dispersively coupled with a pumped optical cavity. Within a semiclassical approximation, we describe the relation between entanglement, spatial organization, and vibrational modes of the ion chain. Upon increasing the pumping strength, our system undergoes a transition from a sliding to a pinned configuration, in which ions are expelled from the maxima of the optical potential. The features of the steady-state entanglement strongly depend on the kind of pinned configuration reached. We identify scenarios leading to entangled steady states, analyze the effect of defect formation upon entanglement between different system partitions, and observe the presence of multipartite quantum correlations.
