论文摘要
在量子纠缠理论中,可分离性是一个重要的问题。通过使用可观察的量子状态的量子状态的Bloch表示,我们为两部分量子系统提供了一个新的可分离性标准。结果表明,该标准可能比检测纠缠的先前标准更好。结果推广到多部分量子状态。
Separability is an important problem in theory of quantum entanglement. By using the Bloch representation of quantum states in terms of the Heisenberg-Weyl observable basis, we present a new separability criterion for bipartite quantum systems. It is shown that this criterion can be better than the previous ones in detecting entanglement. The results are generalized to multipartite quantum states.
