论文摘要
研究了由值和谐波振荡器组成的两分系统中的纠缠动力学，仅通过与同一浴缸的耦合相互作用。该考虑的模型假设量子位通过Jaynes-Cummings相互作用耦合到浴室，而振荡器的位置通过偶极相互作用耦合到浴室的位置。我们为被考虑的模型提供了Gorini-Kossakowski-Sudarshan-Lindblad方程的微观推导。基于Kossakowski矩阵，我们表明包括纠缠在内的非古典相关性可以由所考虑的动态产生。然后，我们在分析上确定生成纠缠的特定初始状态。我们的数值模拟也支持了此结果。
The entanglement dynamics in a bipartite system consisting of a qubit and a harmonic oscillator interacting only through their coupling with the same bath is studied. The considered model assumes that the qubit is coupled to the bath via the Jaynes-Cummings interaction, whilst the position of the oscillator is coupled to the position of the bath via a dipole interaction. We give a microscopic derivation of the Gorini-Kossakowski-Sudarshan-Lindblad equation for the considered model. Based on the Kossakowski Matrix, we show that non-classical correlations including entanglement can be generated by the considered dynamics. We then analytically identify specific initial states for which entanglement is generated. This result is also supported by our numerical simulations.
