چکیده

We study monogamy and polygamy inequalities of unified entanglement in multipartite quantum systems. first derive the inequality unified-(q, s) for multi-qubit states under arbitrary bipartition, then obtain $$\alpha $$ th ( $$0\le \alpha \le \frac{r}{2}, r\ge \sqrt{2}$$ ) power formation tripartite their generalizations states. also generalize bipartition. Moreover, we investigate $$\beta \ge \mathrm{max}\{1, s\}, 0\le s\le s_0, s_0\le $$2\otimes 2\otimes 2$$ n-qubit Finally, using detailed examples, show that results are tighter than previous studies.

Monogamy and Polygamy of Entanglement in Multipartite Quantum Systems

One distinct property of quantum entanglement from other classical correlations is that multipartite entanglements cannot be freely shared among the parties: If two parties in a multi-party system share a maximally entangled state, then they cannot share any entanglement with the rest. This is known as monogamy of entanglement (MoE) [1], which is a key ingredient for secure quantum cryptography...

Monogamy, Polygamy and other Properties of Entanglement of Purification

For bipartite pure and mixed quantum states, in addition to the quantum mutual information, there is another measure of total correlation, namely, the entanglement of purification. We study the monogamy, polygamy, and additivity properties of the entanglement of purification for pure and mixed states. In this paper, we show that, in contrast to the quantum mutual information which is strictly m...

Multipartite entanglement indicators based on monogamy relations of n-qubit symmetric states

Constructed from Bai-Xu-Wang-class monogamy relations, multipartite entanglement indicators can detect the entanglement not stored in pairs of the focus particle and the other subset of particles. We investigate the k-partite entanglement indicators related to the αth power of entanglement of formation (αEoF) for k ≤ n, αϵ and n-qubit symmetric states. We then show that (1) The indicator based ...

Multipartite entanglement in qubit systems

We introduce a potential of multipartite entanglement for a system of n qubits, as the average over all balanced bipartitions of a bipartite entanglement measure, the purity. We study in detail its expression and look for its minimizers, the maximally multipartite entangled states. They have a bipartite entanglement that does not depend on the bipartition and is maximal for all possible biparti...

Monogamy of Correlations vs. Monogamy of Entanglement

A fruitful way of studying physical theories is via the question whether the possible physical states and different kinds of correlations in each theory can be shared to different parties. Over the past few years it has become clear that both quantum entanglement and non-locality (i.e., correlations that violate Bell-type inequalities) have limited shareability properties and can sometimes even...
