We investigate the monogamy relations of multipartite entanglement in terms of the α th power of concurrence, entanglement of formation, negativity and Tsallis-q entanglement. Enhanced new monogamy relations of multipartite entanglement with tighter lower bounds than the existing monogamy relations are presented, together with detailed examples showing the tightness. These monogamy relations give rise to finer characterization of the entanglement distributions among the subsystems of a multipartite system.

多量子位系统中增强的一夫一妻制关系

我们研究了多方纠缠的一夫一妻制关系，即并发的 α 次幂、形成的纠缠、否定性和 Tsallis-q 纠缠。提出了具有比现有一夫一妻制关系更严格的下界的多方纠缠的新一夫一妻制关系，以及显示这种紧密性的详细示例。这些一夫一妻制关系产生了对多方系统子系统之间纠缠分布的更精细表征。
