摘要：We establish a characterization of multi-qubit entanglement constraints in terms of non-negative power of entanglement measures based on unified-( q , s ) entropy. Using the Hamming weight of the binary vector related with the distribution of subsystems, we establish a class of tight monogamy inequalities of multi-qubit entanglement based on the α th-power of unified-( q , s ) entanglement for α ≥ 1. For 0 ≤ β ≤ 1, we establish a class of tight polygamy inequalities of multi-qubit entanglement in terms of the β th-power of unified-( q , s ) entanglement of assistance. Thus our results characterize the monogamy and polygamy of multi-qubit entanglement for the full range of non-negative power of unified entanglement.
