摘要

在我们的工作中引入了纠缠测度E平方的一夫一妻制的扩展概念。代替传统的CKW不等式,我们基于参数\(\mu \)建立了一个一夫一妻关系,由此我们得到了纠缠测度的\(\alpha \)次幂(\(\alpha \ge 2\))次方所满足的一夫一妻关系。我们用具体的例子来说明这种关系的意义和优势。我们进一步证明,通过考虑违反CKW不等式的每个非加性纠缠测量的多个状态副本,可以恢复一夫一妻制关系。我们还展示了如何加强三方国家和多党制之间的关系。

Quantifying the Parameterized Monogamy Relation for Quantum Entanglement with Equation

An extended concept of monogamy for the square of entanglement measure E is introduced in our work. Instead of the traditional CKW inequality, we build a monogamy connection based on the parameters \(\mu \), from which we obtain a monogamy relationship satisfied by the \(\alpha \)th (\(\alpha \ge 2\)) power of the entanglement measures. We use concrete instances to highlight the significance and advantages of these relation. We further show that monogamy relationship may be restored by considering multiple state copies for each nonadditive entanglement measurement that violates the CKW inequality. We also demonstrate how the relationship between tripartite states and multiparty systems might be strengthened.

期刊介绍: International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
