We study the distribution of quantum correlations characterized by monogamy relations in multipartite systems. By using the Hamming weight of the binary vectors associated with the subsystems, we establish a class of monogamy inequalities for multiqubit entanglement based on the $$\alpha $$αth ($$\alpha \ge 2$$α≥2) power of concurrence, and a class of polygamy inequalities for multiqubit entanglement in terms of the $$\beta $$βth ($$0\le \beta \le 2$$0≤β≤2) power of concurrence and concurrence… CONTINUE READING
