We consider multipartite states of qubits and prove that their bipartite quantum entanglement, as quantified by the concurrence, satisfies a monogamy inequality conjectured by Coffman, Kundu, and Wootters. We relate this monogamy inequality to the concept of frustration of correlations in quantum spin systems.
我们考虑量子比特的多体状态，并证明其由并发度量化的二分量子纠缠满足由科夫曼、昆杜和伍特斯猜想的一夫一妻制不等式。我们将这个一夫一妻制不等式与量子自旋系统中关联的受挫概念联系起来。
