论文摘要
量子纠缠是量子信息处理和量子计算中的核心资源。有效地表征量子状态的纠缠是一个重大挑战。最近，[Phys。莱特牧师。 Elben等人的125，200501（2020）]。基于前三个部分转移（PT）密度矩阵的力矩。然后在[Phys。莱特牧师。 127，060504（2021）] yu \ emph {et al。}提出了两个基于PT矩的通用强大标准。在本文中，根据矩阵的重组操作，我们提出了这种重新调整时刻的纠缠检测标准。我们通过详细的例子表明，调整矩也可以用于识别量子纠缠。
Quantum entanglement is the core resource in quantum information processing and quantum computing. It is an significant challenge to effectively characterize the entanglement of quantum states. Recently, elegant separability criterion is presented in [Phys. Rev. Lett. 125, 200501 (2020)] by Elben et al. based on the first three partially transposed (PT) moments of density matrices. Then in [Phys. Rev. Lett. 127, 060504 (2021)] Yu \emph{et al.} proposed two general powerful criteria based on the PT moments. In this paper, based on the realignment operations of matrices we propose entanglement detection criteria in terms of such realignment moments. We show by detailed example that the realignment moments can also be used to identify quantum entanglement.
