Tighter constraints of multiqubit entanglement for negativity
Long-Mei Yang, Bin Chen, Shao-Ming Fei +1
We provide a characterization of multiqubit entanglement monogamy and polygamy constraints in terms of negativity. Using the square of convex-roof extended negativity (SCREN) and t…

Tighter constraints of multiqubit entanglement
Long-Mei Yang, Bin Chen, Shao-Ming Fei +1
Monogamy and polygamy relations characterize the distributions of entanglement in multipartite systems. We provide classes of monogamy and polygamy inequalities of multiqubit entan…

Tighter weighted polygamy inequalities of multipartite entanglement in arbitrary-dimensional quantum systems
Bin Chen, Long-Mei Yang, Shao-Ming Fei +1
We investigate polygamy relations of multipartite entanglement in arbitrary-dimensional quantum systems. By improving an inequality and using the th () power of ent…
