论文摘要

使用非常普遍的论点,我们证明基于距离的任何纠缠措施都必须在纯状态上最大。此外,我们表明,纠缠纠缠和纠缠的几何测量的bures措施满足了所有纯多Quibit状态的一夫一妻制不平等。最后,利用Bures纠缠和纠缠的几何测量的衡量标准,我们为多Quipit系统的纯状态提供了一类紧密的一夫一妻制关系。

Using very general arguments, we prove that any entanglement measures based on distance must be maximal on pure states. Furthermore, we show that Bures measure of entanglement and geometric measure of entanglement satisfy the monogamy inequality on all pure multiqubit states. Finally, using the power of Bures measure of entanglement and geometric measure of entanglement, we present a class of tight monogamy relations for pure states of multiqubit systems.
