研究了耦合双Tavis-Cummings模型中三体纠缠态的演化和转移特性。结果表明, 初始局域的三体W型纠缠态可以转移为另外局域的三体纠缠, 在纠缠转移过程中, 两光腔场的耦合参数起到了重要的作用。随着耦合参数的增加, 三体纠缠的转移速度加快。并且初始三体纠缠在演化过程中不会完全被局域子体系间所俘获, 还会转移到其他非局域子体系上。最后, 我们还分析了腔场间耦合强度对初始三体量子态演化速度的影响。

The tripartite entanglement evolution and transfer of the double Tavis-Cummings model were investigated.The results showed that the initial local tripartite entangled state (W-like state) can be transfered to another local tripartite entanglement.In the process of entanglement transfer, the coupling parameter of two light cavity fields played an important role.The tripartite entanglement transfer speeded up when this coupling parameter increased.The initial tripartite entanglement could not be fully captured by the local subsystems in the evolution process, and would also be transferred to other non-local subsystems.Finally, we also analyzed the effect of the coupling strength between two cavitys on the evolution speed of the initial tripartite entangled state.
