Tighter constraints of multiqubit entanglement in terms of unified entropy
arXiv:2110.11565 · doi:10.1088/1612-202X/ac2cd0
Abstract
We present classes of monogamy inequalities related to the -th () power of the entanglement measure based on the unified-() entropy, and polygamy inequalities related to the -th () power of the unified-() entanglement of assistance by using Hamming weight. We show that these monogamy and polygamy inequalities are tighter than the existing ones. Detailed examples are given for illustrating the advantages.
