Tighter Constraints of Multipartite Systems in terms of General Quantum Correlations

Quantum Physics 2022-02-07 v1

Abstract

Monogamy and polygamy relations characterize the quantum correlation distributions among multipartite quantum systems. We investigate the monogamy and polygamy relations satisfied by measures of general quantum correlation. By using the Hamming weight, we derive new monogamy and polygamy inequalities satisfied by the β\beta-th power and the α\alpha-th power of general quantum correlations, respectively. We show that these monogamy and polygamy relations are tighter than the existing ones, such as [Int. J. Theor. Phys. 60, 1455-1470 (2021)]. Taking concurrence and the Tsallis-qq entanglement of assistance as examples, we show the advantages of our results.
