多量子比特纠缠的更严格约束

Tighter constraints of multiqubit entanglement

Long-Mei Yang, Bin Chen, Shao-Ming Fei, Zhi-Xi Wang

摘要:

一夫一妻制和一夫多妻制是多体系统中纠缠分布的特征。分别从纠缠度、形成纠缠度、负性、Tsallis- $q$纠缠度和Rényi- $α$纠缠度等方面给出了多量子比特纠缠的单偶和多偶不等式.对某些量子态,我们证明了这些不等式比现有的不等式更严格。

英文摘要:

Monogamy and polygamy relations characterize the distributions of entanglement in multipartite systems. We provide classes of monogamy and polygamy inequalities of multiqubit entanglement in terms of concurrence, entanglement of formation, negativity, Tsallis-$q$ entanglement and Rényi-$α$ entanglement, respectively. We show that these inequalities are tighter than the existing ones for some classes of quantum states.
