三分量子比特系统的可分性判据

Separability Criterion of Tripartite Qubit Systems

Chang-shui Yu, He-shan Song

摘要:

本文提出了一种构造三量子比特系统完全可分性判据的方法。我们的方法的精神是,一个三方纯态可以被视为一个三阶张量,提供了一个直观的数学公式的纯态的完全可分性。我们将这一定义推广到混合态,并给出了相应的完全可分性判据。作为应用,我们讨论了几种束缚纠缠态的可分性,结果表明我们的判据是可行的。

英文摘要:

In this paper, we present a method to construct full separability criteria for tripartite systems of qubits. The spirit of our approach is that a tripartite pure state can be regarded as a three-order tensor that provides an intuitionistic mathematical formulation for the full separability of pure states. We extend the definition to mixed states and given out the corresponding full separability criterion. As applications, we discuss the separability of several bound entangled states, which shows that our criterion is feasible.
